XXXX Bank took over a credit card account that I had with another company and raised our interest rates by 150 % without our knowledge or written notice. I contacted them about their deceit and the inappropriate raise in our APR and they said that I could pay off the debt but that was the only way to stop the interest accrual but they would not take back the extra interest already added for the previous months which totaled about a {$700.00} dollars. I paid off the account except for the {$700.00} that I felt was a malicious way to increase their bottom line when they had just received a bailout from the government. They kept adding interest to the interest and then sold the debt to another company. I contacted them and told them that this debt was paid and that they were trying to collect on interest charges that were illegally accrued on my account without my knowledge and that XXXX bank had kept adding interest to an already balance that was only interest in the first place. They never contacted me again but this has damaged my credit. I am sure that this has happened to many many people and that they paid the extra interest without questioning XXXX Banks practices. My credit card account was always paid on time and I had a 9.5 % interest rate when XXXX took over they had raised my APR ( without my knowledge XXXX to 25 % and this all happened after they received their government bailout. I have copies of all my statements and records to back up my claim and when I contact XXXX back and asked them to send me a copy of their letter that they stated they had sent to me about the raise in my APR, they mailed my a shrunken copy of their new customer pamphlet that the print was so small you could not even read it.
