We signed up for Tribal Merchant Srevices. Seemed to be ok until a year ago. I was doing payroll and noticed a stange debit in my companies online checking account. The $185 charge was not something I could identify. I called my bank, they told me to call the number listed next to the charge. Turns out it was Tribal. They had removed $185 for a PCI compliance charge without authorization. When I confronted them they said they had mailed me a letter. I never received a letter and knew nothing of their claim I called my representative who had sold me on Tribul in Billings, Montana. He called me back eventually and said he had gotten the charge reduced to $100; but it was going to be an annual fee. I started looking for a replacement company. In February of 2011 I switched companies. Tribul continues to this day to deduct $35 every month on the 6th. I have written them, faxed them asking for a cancelation and refund. So far they have deducted $105 from my account unauthorized. I may have to change banks and get a new account, new checks, deposit slips, etc. to end this. It is outright theft.
