Vodacom contract canceled for no reason.

Poor service I received from Vodacom. I converted my sim to a 50G data contract in April 2023. A month later my sim got blocked every two days and had to visit their outlet to have it unblocked since they couldn't do it over the phone. I did this for over twenty days. Every time I was told it will not happen again. Finally I was told it was a system error. Two days later it was blocked again, when I visited vodacom in Richardsbay I was told they couldn't access my account since my number was cancelled. I was given a replacement sim with a different number that I need to recharge. This is frustrating and a huge inconvenience since I use data for my work.
