Poor service from Vodacom

I have a contract with Vodacom ( account number i***-6) which was R6,133.45 on arrears which I paid on the 18th of February 2023 but what surprises me is the said amount reflects as a monthly installment. I phoned Vodacom since Monday until today, no one assisted me but I was given numbers to call which was a waste of time. ***,082135,***4 and the last one was worse its no longer in use but the consultant gave it to me *** .I can't even view the statement on my Vodacom app
