Shockingly Inefficient Accounting Dept

I received a notification from Lancet to pay an amount which was not covered by my medical aid. A small sum of R233, which I had no problem paying. The lady that phoned me was helpful, and sent me an e-mail to my phone, which had the added bonus of a PayFast link which made it comfortable for me, as I was travelling. I then used the payfast EFT link, paid the money, and it was sorted. Or so I thought.

Now, they haven't been able to allocate the payment, and have been hounding me for a proof of payment. If I understand correctly, Payfast creates a temporary beneficiary, and I can't view a proof of payment as it goes through their portal? I sent them screenshots of the sms notifications I got throughout the PayFast process. Thereafter they sent a generic e-mail stating that they needed a "actual" proof of payment. After I told them I made use of PayFast. I asked if I can send a bank statement, to which they rep****- yes. I then sent the bank statement- and guess what? They rep**** with the same generic e-mail stating that they needed a proof of payment. I will never make use of you again, for the simple fact that you have been wasting my time for weeks now. I hope we can sort this out. Otherwise, I will just pay the R233 AGAIN to get rid of you. It seems like a small price to pay to rid myself of the frustration of dealing with you.
