Tax Group Center I was ripped off by this company Calabasas

 Hello the 11th month the 16-day of 2017 I paid $2,500 for a tax resolution. I pay with my bank credit card. Tax Group Center to get a deduction or to get them to ddelete my Texas and start new in 2017. I call within a three days time. To cancel out but I was given the run-around. I left messages when I call I called the bank to stop payment on my credit card which they did. In December text group Center call me and request that I dropped or cancel the dispute with the bank I told them I was assuming all was okay. He said no and if I didn't cancel the dispute to stop payment at the bank I would be made to pay the full amount of $2,500. In January text group Center call me to tell me that they won the arbitration and that I would be made to pay the $2,500. I call cardmember service and cancel my card which I only had a balance of $400 on my credit card at the time. In January the bank rebuilt my account for $2,500 I called the bank about this but it was yet charged even after my account was closed. I feel I was ripped off by this company because they didn't do anything for me whatsoever . They refuse to give me back my 2500 on my credit card they sent me a letter with charging amount of $1,555 but they didn't do anything . They said they would refund me $945 which I feel is wrong I was ripped off by Tax Group Center. Can you please help me get my refund back I was ripped off by this company. I do not have 2500 to pay for something I didn't receive please help me. Thank you so very much
