<prompt> Human: So, long story short, I had no credit, no 1 would give me a credit card. The banker at Capital One tells me I should get a prepaid credit card, for which I have to put down a 500 dollar deposit. She tells me this is a good option for me, because it reports to credit agencies, building my credit score, and she told me after year, it converts to a regular credit card and I would have my deposit returned to me.Fast forward a year and a half later, I go into the bank and try to ask for my deposit back and they said Oh no, no such thing happens with the prepaid card. To get your deposit back you have to close the card. I asked for the banker, and she no longer works there.How should I proceed from here? I dont want to close the card, because it is my longest, and only line of credit. If I close it, I lose all of that good credit history. This card alone is responsible for bring my credit score up to 735. On the other hand, I dont just want to let my 500 slip through my fingers that way. Why should I kiss my money goodbye because this banker lied to me?  <response>: Get a better card, close your old one? Having a decent credit score is important, but not 500 important.
