Pethetic service from vodacom

I phoned into vodacom customer care on the 23 February 2025 to cap the account or limit the usage, where after what was given to me in the contract that i shouldn't acceed the limit it should stop working the consultant told me that it was done the following month I got a bill of +-R1600, I then called in an complained an the asked for the limit to be capped again, the following month i got billed +-R1500, I phoned in again asked for the limit to be capped an got a bill of R1200 after speaking to the consultant again asking for the contract to be capped she informed me they tried calling so they closed my query an I said I spoke to the person an she told me that I will be credited an they will minus my normal amount off +-r350 from what was debited from my account over those months cause I did ask for the account to be capped in February till the what's owing to me is settled an that I will not be debited till the credit owing to me is settled then they will continue the normal debit amount, ive delt with telkom for 10 to 15 years an never had this problem once changing to vodacom was the biggest mistake I have ever made people beware when other friends told me about their terrible experience from vodacom I didn't listen an this is what I got for not listening
