Confusing and untrue statements from payflex

I contacted Payflex as i suddenly last night this morning had a R0 balance to spend. I couldnt understand as the day before i paid up so many orders and installments. I emailed payflex and Lindiwe said its because of my credit score that was too low and not favourable. What utter nonsense! I checked Splendi and Clearscore and im ‘good’ according to them. I also try and pay my payflex installments ahead of time. BUT a few hours later this morning suddenly i have a R6500 spending balance. What confusion this creates! Im not impressed with payflex and how they deal with this issue. Makes we wonder how safe this site is. Also sometimes when you pay off order in totality it still shows under ‘current’ for a while.
