WiFi never delivered - only offered a myriad of excuses

I ordered and paid for a new wifi router telephonically on the 24th of October. My current ISP contract was coming to an end on the 31st, and with the promised 3 - 5 day delivery time, I was sure that my new router would be delivered and set up in time to ensure seamless connectivity as I work from home. On the 29th of October, having not heard from the courier company as promised, I reached out to MTN enquiring if I would receive my router in time. They responded that the courier service had my address saved incorrectly and that the issue had been corrected. By the 3rd of November, I was working from home via a very expensive hotspot on my cell phone and getting nowhere with mtn customer service. After several reports that the postal code I provided was incorrect, suddenly I have been told that my order was cancelled because there was no card on the system. Because I opted to pay via debit order and did not give them card details. I paid R500 upfront and can only hope that they are more competent at refunds than they apparently are at correctly capturing addresses and bank details. This has been the biggest waste of time, energy and money.
