the toll-free numbers??

800-955-6600 is the number of Capital One. They are the original company hence, allowed to make collection calls. They are not bound by any laws in calling people. They will continue to do so until some solution is worked out.

It will be good for you to arrange something at this stage before they send your file to some debt collector. A collection is a negative entry with a R9 rating and lowers your credit scores by 100-150 points. Experiences with these people are also very painful.

It's Capital One calling to try to collect on a credit card bill.
In Texas and Florida, they CAN NOT COLLECT on an unsecured account
like a credit card. Ask a lawyer. Texas and Florida are debtor states and even if they go to court and get a judgement, they cannot collect an unsecured judgement. Again, ask a lawyer. You probably dont have to file bankruptsy or anything. It helps if you can just change your phone number every few months. In other states they CAN collect if you have assets, bank accounts and even levy part of your wages. BUT NOT IN TEXAS and FLORIDA. Ask a lawyer in those states. If they trick you and get you to sign a judgement that GIVES THEM a secured interest in your assets, that's too bad. You should not convert an unsecured debt into a secured debt.
