MTN SA did me dirty!!!!

I have been trying to cancel my month to month sim card deal since 2020,due to the fact that i was overcharged on my debit orders instead of deducting R350 I have been paying about R700

That was not even pro-rata fee,till today I'm still struggling to get through to contract unit!

I called about 100times with no luck

I am honestly NOT happy with the service MTN SA is rendering to me
