I closed my Credit One Bank card because they claimed I exceeded my credit limit. I had sent them a check paying off half my balance and they did not credit my account with this payment until a week and a half after their statement came out. Then they contacted the credit bureau and charged me with exceeding my credit limit which caused my credit rating to fall 41 points. I wrote them a long letter chastising them for lying to the credit bureau and I sent them documents showing their lie.
I also sent them a letter canceling my account after I had paid the account off. I just received a statement from them claiming I owe them $508.00. I checked these charges and they are all false and I have the evidence. They filed false charges (purchases) on my credit card account and lied about credit card balances to Credit Bureaus. They are headquartered in Las Vegas, Nevada.
