MTN South Africa Appalling Customer Service

I'd renewed my contract in June 2022, August 2022 the phone became faulty so handed it first to MTN St Georges Mall Cape Town. About a month later was told I needed to take it to MTN Century City as it was an online upgrade. I did that as well and was given an 012 number to call after about a week to check on progress of the repair; which i did as well. My contract got cancelled as the phone was deemed unrepairable, and was advised I need to call MTN to get credit refund of R750.00 initially. 2 months down the line my issue is nowhere nearing any resolving. As I'm writing this I've been put on hold indefinitely 4 times so that I must hang the call up which i did eventually when waiting about 40 minutes and I could hear people on the background. All this for a credit transfer payment update of R 725.50 which it seems MTN SIMPLY DOESN'T WANT TO REFUND. All these MTN Supposed Champions to name but a few (RETENTIONS DEPT. namely Sindisile, Sazi; ACCOUNT DEPT. Dudu, Lungile and ACCOINTS DEPT. Bulelwa tell me they see the amount reflecting but really and simply refused to help me. I've been a loyal MTN prepaid customer for more than 10 years but this is the way they than you,

Appalled Customer,
