Dr. Fixit ACH Fraud and additional charge when paid by check for 1 visit. Columbia South Carolina

We called Dr. Fixit to repair a fridge that had stopped getting cold. The tech came to our house on 4/28 and diagnosed the problem. Due to the cost and what was wrong we opted to replace the fridge instead of having it repaired. We paid the technician what we owed for him coming out, $85.00, with a check on 4/28 and recieved a copy of the invoice showing paid. Dr. Fixit instead of cashing the check used it to setup an ACH, hich was not authorized, so they could continue to draft from our account. Ths company drafted the $85.00 fee more then once 4/30 and again on 5/7. When we called Dr. Fixit to inquiry about this, we were told no one was avaiable to discuss it with us and had to leave a voicemail. To try and get this resolved I have had to call my bank and dispute this and put a block on the account from them being able to draft anything else from us.
