Capital One Credit Card Complaint

Capital One Credit card department,

Customer service / Customer relations New York

In reviewing my most recent Capitalone statement it came to my attention that, though the beginning balance on my statement was $5000.00 and I made payments during the statement period totalling $4400.00 leaving a remaining balance of $630.00, I was charged over $100.00 in interest for that period. I saw on the statement that the amount that was used to calculate the interest was $5400.00, which made no sense to me. When I called to inquire and ask why the interest was calculated on that amount rather than the $630.00 that represented the remaining balance, - ( laughing ) told me that the interest is based on the " average daily balance '' inclusive of new purchases? I asked her when this changed as I have had this account and used it regularly for nine months, have always followed the same pattern of paying as I go with this account and have never paid any amount of interest before. Continuing to laugh, she said she would refund the $100.00 and make a note in the file. I advised her that in all my years of using credit cards, not - company has ever charged interest on new purchases before the statement is even issued. She continued to laugh and I advised her that I would be contacting you with a complaint. She laughed again. I told her I was happy she was having so much fun on her job. I think it 's time to close this account as I have been hearing this company has not been treating consumers fairly. Now that I have had my own experience, I believe it 's a good idea.
