POOR SERVICE

I accidentally over paid MTN on the 20 December 2024, contacted them and enquired on the refund process. Submitted the requested documents on 22 December 2024. I then received an email from Lindiwe Macekiswana from their back-office support stating that my documents were received, and my refund was processed, and my money will be in my account within 7 working days. I have been calling there 135 number speaking to different "customer service champions" and no one can tell me when I will receive my funds. I have sent emails to their back-office support service, the respond, but from a no reply email address. The back office does not take calls and MTN call center staff can only communicate via notes on the system which they do not reply too. This is absolute horrible service from MTN.
