Business ProfileforStax Payments

Fattmerchant/Stax has been fraudulently taking money monthly from my business checking account for over 3 years. I never signed up for their services or agreed to have my account debited. I filed an application on 3/1/2021, but ultimately decided it was too expensive for my needs and gave them final notice on 3/17/21 that they were not a fit for my business. They claim to have a signed agreement with my digital signature that I have never seen & never agreed to. It was "signed" on 3/1/21 late in the evening - I did not even have pricing info at this time as I had only just initiated contact with them. I have never received any additional information, tax forms, statements, POS devices, communications, letters, anything from them. The amounts withdrawn monthly from my account vary from $54.99 - $242.97. None of these amounts were provided when I began the initial conversations in 2021 to evaluate their credit card processing services as a fit for my business. They also claim I have a POS device - I do not and have never received any equipment from them. My transaction history with them is zero every month since March 2021 because I did not agree to use their services and have never processed a single payment through them. I have gone to their offices in ******* and was directed to their legal department. A demand letter has been send from my attorney on 6/28/24. We have not received any response or follow up communication. The digital signature audit trail only refers to signatures on an application and there are no incidences of signatures on an agreement. I am demanding a return of $4,129.22 for the fraudulent charges deducted from my bank account without my permission from 6/8/21 through 5/7/24. ****'s customer support manager claims to have canceled the account on 7/21/24, but I continue to receive outstanding balance notices through ************* I never agreed to this & had zero idea I was being charged until a recent audit caught the mystery charges.
