Unbelievable service

settled a loan and RCS card account unfortunately i had paid way to much , made contact with them and now an uphill battle to get my money back. i was told the 14 of February that it would take 36 days for them to close my RCS card account but no charges will be added, guess what they added a month charges and had not gave me a refund yet.How can our government let companies like this thieving ********* still do business. they acknowledge that i do not owe them a cent and that they owe me money that i over payed them. People please if you can just stay away from the RCS group.
