Worst service

I made a payment into the Car track bank account on 30.04. 2020.I forgot to include a 8 in my reference number. I called to confirm if the payment was received, because of the incorrect reference it wasn't. I sent a proof of payment to Siphokazi Ndamase on 6.05.2020.She did not contact me after receiving the proof of payment. I called today 08.05.2020 and spoke to Michelle. She advised Siphokazi said she received the proof of payment and will call. No call received nd payment not allocated.
