<prompt> Human: I love my family. However, my family and I are not on the best of terms. Today I woke up to my nightmare. After talking to my parents on the phone they started mentioning money and how they know I need help. Need help? How would they know anything about my financial affairs?It turns out my bank- SANTANDER has been sending all of my bills bank statements to my mother and father who live on the other side of the country.Why would they do this? Well I had a family bank account with them about 4 years ago.The company was called Sovereign back then I closed this after spending a lot of money paying fees associated with the account.Once I got a job and started working earlier this year I decided it was time to open my first personal bank account. I was excited to move forward with my life. I decided to use Santander because they are local and have ATMs everywhere.I made the account and started receiving money in it. When I created this new account I made sure to use my up to date billing information. The next time I talked to my parents I was pretty shocked and upset. They had been receiving my mail from santander and knew exactly how much money I had earned and all the times I used my debit card.I was livid. I moved out and got a job to support myself and prove I can be self-sufficient. Now I have my parents all in my personal information like its highschool again.Well, I went in person to the bank to ask them what had happened and to ask them to change the mailing addresses.They told me my new bank account was still linked to my old family account in their system.They said they would make sure the accounts are no longer linked, change my billing address and that my family would no longer receive any mail from santander.Well I just got off the phone with my parents and they are still receiving my mail and they can still see every purchase I make.I am quite upset because when I went to the bank in person the woman at the front desk didnt seem to care at all. When i told her this was a serious breach of my personal privacy she told me she would change the addresses, but she kinda just brushed me off and called to the next person in line. I had this weird feeling she wasnt going to fix anything. Her manager noticed and came over. She made the changes herself... and I still have this problem.I am worried if I go in and ask them to fix this problem that it will just happen again. Will they ever take me seriously? I dont know who else to ask. I feel so trapped. Any advicehelp would be greatly appreciated.edit: locationbot asked for it I live in Boston and yes I really dont want to change banks. The amount of santander ATMs around me versus other banks ughh I really dont want to have to get another bank.  <response>: 1. There is no way they could have linked your personal accounts with the address they have on file for your family accounts. There will definitely be a paper trail when it comes to those sort of links between accounts. Someone would have had to signed something agreeing to it. Go straight to the bank manager and ask to see who connected those accounts. They can also pull what date which employee approved that address change. Dont waste your time with the teller. Go straight to the manager and calmly say youd like to speak to them about the address on your account being changed without your consent.2. If you think you still want to receive statements but definitely dont want them going to your parents address, enroll in electronic statements. There are very few bankscredit unions in 2015 that dont allow you to receive a PDF of your statement on your online banking. And no offense intended, but if your bank doesnt offer that service then you should probably close that account and find a more customer service friendly bank.3. If you remember the name of the women who treated you like you werent an important member of their bank, file a complaint. No one should leave their bank feeling as if they werent taken seriously. There are plenty of other financial institutions out there that will treat you like you deserve and value your membership. And just a side note, Bank of America is NOT one of those banks.Source: Have been working for a larger credit union in the San Diego area for years.Sorry to have written so much but I recently dealt with this kind of problem. Wishing you the best of luck OP.
