Pathetic service

I have been a client of MTN for the past 10+ years. I recently took a month to month wifi deal, biggest mistake ever. From the start information given to me was incorrect, my account was debited only to be told that the data will only reflect the following month. I took all the equipment and returned and cancelled this contract on the 5th July 2023, till today I have not received my refund. I have spoken to Imthiaaz from MTN Amajuba Mall Newcastle, who seems to know nothing about MTNs products,policies and procedures. Was then assisted by Siya who seems to be getting no feedback from MTN head office, then called BNB and spoke Thea, who is just as confused and basically just tells me exactly what I already know. The incompetency is actually quiet scary for such a big and popular brand. One things for sure is I am no longer going to deal with MTN ever again, absolutely pathetic service.
