Vodacom *****, Theft????

So our business has a few lines with Vodacom at different sites @ fixed amounts with the occasional top-up sometimes. Last year November we received a bill was for 17k. Now we have contracts with them for a set amount so our bill every month should be set and we have a debit order on our account. So when this bill came I had to do a recon and I found that Vodacom has been duplicate charging us since August 2023!!! I reconned the account and sent them a query for which they send a reference number and then nothing else!! They don't call or email you back to advise you what is happening!! I tried calling them but unfortunately, I was told, that there is no way to contact their finance department directly.... only through emails! In December 2023 we received a credit on our account for half of what I think they should credit us and they don't give any description on the credit note other than "Billing Adjustment" I sent them another email asking them to explain this and for someone to please call me to discuss this, but still no response!!

I have tried all avenues that I can think of and I have no idea what else to do. This is theft! Vodacom sells you this lovely picture of their services when in actuality they are pathetic! We are a business not just an individual. We should at least have an account manager that can contact us with this!!

How many companies are they doing this too I wonder.

I hope this gets someone's attention and it can be resolved.
