Telkom mobile contract to prepaid

went in to telkom shop in Paarl Mall on the 4th March and asked to cancel my mobile contract and change to prepaid, was told it would happen at the end of the month March 2021, i have over R400 airtime, the next morning my phone was switched off,we went back to Paarl Mall and my husband was very badly treated told him the contract was cancelled 6 yrs ago and he is a chancer and whats the problem you had no credit anyway, so we left , phoned the help line after spending 4 hrs trying to get through to the right person the lady said it shouldnt have happened and would re-instate our number within 48 hrs, phoned again today and was told we only have data on our phone and we were talking nonsense and she put the phone down on my ear.we have never had data on our mobile phone.
