Hello,
I use QB merchant service. I was charged 1844.59 twice for a sales order I created in QBO rather than an Invoice. I had no Idea that when I saved the sales order it automatically charged the customer credit card 63,597.88. the customer called me 2 days later when they got notice from AMEX that this charge was on their card. I went to my QB merchant account and refunded the 63,597.88.
I reached out to QB Merchant services and they said sorry your out the 3689.18 . So for a simple mistake it cost me 3689.18 I have had an account with them for at least 15 years without any chargeback ever. So much for helping out small business.
