Poor customer service

I've been using Payflex for years and I've never experienced the experience I'm experiencing right now, Friday it was my payment date and the payment was declined because I was still waiting for my salary to be in, and I received an email stating that my card has been blocked and will be unblocked at 14:45, and immediately when my money was in at 11:00 I tried making a manual payment with no success until today, I even paid for my other order that I was supposed to pay on the 1st of May, I tried several times to send queries but all I'm getting is no reply response that tells me to do the same thing I've been trying this whole time, and the worst part about this, they have added the late charge, Payflex customer service is a whack, I'm very disappointed 😞😞😞
