Vodacom makes more problems

I keep on having problems with Vodacom! When they make mistakes they don't fix all the problems they created and that is my biggest problem with this company. In June I paid for my account on the app and showed me payment was made money was deducted from my bank. Before end of the month they messaged me payment was not made so I contacted Vodacom spoke to 4 to 5 different agents I sent my bank statements to show proof of payment they told the problem was the money was not allocated to the account and they would fix it. Next month still sitting with the same problem so I did a review on Hellopeter then they quickly tried to fix the problem but didn't receive any feedback at all just said problem is fixed but sorry Vodacom it was never fixed now the have negatively affected my credit score. I will now have to take Vodacom to NCR if they don't fix this issue
