Vodacom - THE WORST

I have had the WORST experience with Vodacom over the last year. First they notified me a YEAR too early of an upgrade due, which resulted into me still paying off my previous handset (this is partially my fault as I should have realized I am not due for an upgrade as yet).

According to my conversation with them a few months ago, my last installment due for the old handset was Jan 2020 - Then they deducted R1400.00 from my account today for settlement of my handset?! HOW?! This is not even what I still owe for that handset. This is *****!! When I phone them this morning the call lasted 1 hour and the matter has been "escalated".

Vodacom's service has been poor and extremely disappointing. For the amount of money I pay to Vodacom in a month I definitely expect way better customer service.

Is there some place I could report Vodacom to? I will not leave this matter and most certainly not pay the R1400.00.
