Vodacom Pathetic Service Not One Person to Help

During level 1 lockdown I phoned Vodacom to notify them that I am a wedding dj and was unable to pay my account. I also queried my one contract and asked them to put one of my cellphone numbers on prepaid to which they told me that it was. For a period of time I never received airtime on the number. Paid my account in full. All of a sudden they started sending me airtime on a number that they told me was on prepaid. Now with the curfew there are no bookings and Vodacom's collection service says that they can't do anything with the contract. THEY PROVIDED AIRTIME ON A PREPAID PHONE WITHOUT MY PERMISSION. The collections department say that all they want is arrangements for payment. NO ONE FROM VODACOM WILL HELP WITH MY ISSUE
