<prompt> Human: Hey PF,I accidentally locked myself out last night. I used Google to search for a locksmith. Found a website that offers 15 service call with residencial lock opening starting at 35. I call a woman, she says the 15 is included and tell how difficult the lock is to the locksmith after I asked her for price confirmation. I received a call from the locksmith afterwards and I tell him about the lock, he wouldnt quote me on a price until he got there. Once he arrived, the looks at the lock and shoves an invoice to me with 280 total. He blames the difficulty on the lock and the pricing on the company overhead and the cost to advertise with Google, claims he only makes 15 off this. He pops the door open with ease. Im asking PF if i should use a charge back on this because of the feeling that I have been baited and switched to have the website go from 50 in price expectations to 280, I felt really deceived that they wouldnt quote me until they had me right in front of the door when I needed them the most. Other questions, does charge back affect credit ratings? Also, of this is a parent company and the locksmith isnt an individual contractor, the locksmith wouldnt be coming after me because the company has the charge back? Id like to hear how these work a little more. Thank you guys, you guys are great!  <response>: You arent describing a chargeback. You knew the price 280 was on the invoice before you gave the locksmith authorization to proceed with the work. If you didnt want to pay 280 you needed to tell him to leave and not let him work on your lock. If the company charged you 280 after giving you an invoice for 50, or charged you the 280 even though you told the locksmith to leave because he was too expensive and he did not do the work those would be examples of a valid chargeback. False advertising only works as a chargeback claim when you werent notified of the true price prior to authorizing the purchase. Now, you have an excellent reason to complain about this company in online reviews, file a complaint with a local govt org that oversees these type of businesses, etc.
