Terrible customer servive

Their service is terrible, they have no customer support whatsoever. I made a payment using their app and the payment was not credited to my account even after the app told me it was successful, the money was deducted from my bank account, I then tried calling them to resolve the issue and everytime I do it says "there are no available agents in the que at this moment" even though I call during business hours, I sent a number of emails as well on their support line and none of them were responded to and till now I have not been assisted.

Safe to say I will not be using payflex ever again
