Bad service

I'm so disgusted with Vodacom!!!!!!! I made an arrangement on my account due to lockdown. After my arrangement my account was billed for 2 months, after I had to re contact them to make a new arrangement for these 2 months that wasn't even my fault it was due to a system error!! After this arrangement was made I got billed for another month after I was told I will not be billed!!!! The a manager / supervisor named Josias promised me this will be sorted out, the day after that my phone was reversed with only the data, airtime and sms's and my account still the same!! After numerus calls and an e-mail I get no call back or answer on my account!!!! HOW LONG DO I HAVE TO WAIT FOR A CLICK OF A BUTTON TO REVERSE A MONTHS BILL???????????????????? I HAVE NEVER BEEN BEHIND ON ANY DEBIT ORDER BUT THIS IS THE SERVICE YOU GET!! IT IS REALLY DISGUTING TO SAY THE LEAST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
