Horrible customer service, horrible company overall.

My biggest regret ever, I have an order of which a payment never through I believe due to technical issues, I manually made the payment the following day. Payflex failed to add the R95 on the system and I paid the amount that was on the account listed as outstanding, To my surprise I got another debit of R192.82+95 even after paying the initial amount, when I rang the customer service the line keeps getting disconnected. I spoke to a representative Ntokozo I sent her her the proof of payment and the issue was not solved, another 95 fee was added making the to R382.82 then today another fee of R95 has been added so payflex keeps adding late fees on money that was paid?
