BAD CUSTOMER SUPPORT: DOUBLE PAYMENT went off, no reinbur*****t

Horrible customer support. A payment that I authorised manually went off and then automatically again. I received an error message to ask for a manual reversal. I have emailed PayJustNow twice since a payment went off double and I want to referse the funds. They don't answer their phone when one calls the call centre and they dont respond on emails. What bad service! I now need to pay double for an error on their side. Please please please offer actual support for your customers.
