****med by vodacom every month

I have never been so disappointed in my life, I have been with vodacom for about 3 years if not 4 years and I have never had an issue with the billing but this year May 2024 everything went south after I did an upgrade which I was due for, the consultant had explained to me how the billing is going to be like and I agreed to the terms but June 2024 and July 2024 vodacome billed me but they say there was no money in my account as the "debit" bounced to my surprise I let vodacom debit every 1st of each month and there is ALWAYS money in my account as all my debits goes through on the 1st and 2nd now vodacom has put me on arrears for June telling me that the money that they debited was not the money they wanted (like what nonsense and ****ming is that?), I then asked them what were your reasons for not taking the money that you were supposed to because there was money in my account I even sent them proof of the money left in my account after they took the money that was apparently not what they wanted, I am now supposed to pay R1444.92 for two months as they say but funny enough money went off my account to vodacom even went to the bank to confirm that, imagine paying for June and July plus August for a phone that I was supposed to +-R500pm and you tell me I am not being ****med.
