Platnium Tax Defenders They took 475.00 from my account. which I've been trying to contact them about. But no one will return my phone calls or emails .But they are steady trying to get money from my account.I really need some help these people has put me in a financial bind that Im struggling to get out of Laa Angeles California

I owe the IRS about 7000 dollars ,I was on payments for 50 bucks a month and had some trouble with my car which lead to me missing 2 payments.So the IRS sent me a letter to pay the whole balance by Oct, but I had untill the 16 of Aug to call them and work something out.So I got nervous cause the letter also read they intend to levy, So I called Optima Tax releaf and.told them my situation and they gave me Platnium Tax Defenders So I talk to Mark Garcia first he said not to worry they would help me and told the charge would be 900 dollars for their services I said ok gave 250.00 right there over the phone from my credit card this was on the 11 or 12 of Aug. 2 days later I decieded to go down to the IRS building myself to speak with them about my failure to pay and they reinstated me no problem at the cost of 89 dollars good for me Im back on payments and dont need Platnium Tax Defenders now .So now the Im calling them and leaving messages and emails every chance I get trying to get a refund on my 250.00 I gave 2 days prior but no response for a week 1/2 .No one returns my phone calls or emails I got proof of every email I sent to them cause I keep them.then on the 31 of Aug they take another 225.00 of my card and Im not even using their services now Im calling about that they still wont return my calls or emails.I had to pay rent and was short 225 .00 that i had to borrow from a familiy member to pay my rent.and then sent me a email on the 5 of Sep telling me my account is negative and how do I exspect to pay for my outstanding balance or my case will be suspended.so that tells me they went back for more money 5 days after they took 225.00..wow!!.
