Billing querry

Good day I had a contract with telkom that expired after that they kept on billing but still giving the data i phoned to find out why this was happening and they said I need to go to an outlet when I went to the out let in pavilion I was told that they can't do it but it can be done online yet the service was down .now all of their platforms that they are using are not being if assistance. Billing continued an it happened that I had no funds in my account donut bounced following month I was charged twice of which that was fair another month went by and I was charged +-R305 if which I reversed as I was not aware what's it for the out let again explained that if a transaction bounced they charge you +- R200 why is this happening after 3 months the incident occured? A call was logged and on the 39th and i spoke to Jason he advised that the bill has been disputed and I will not be charged anything if I get debited I need to go to an out let and they will transfer the funds back in my account. I was there just now and again they don't have a clue what I am talking about I am running up and down waisting time and fuel to have a matter that was poorly communicated resolved . Another call was logged today and I spoke to an agent that was rude and didn't have the time and he also said Jason was telling me lies and doesn't know what he was talking about but who in telkom knows what they talking about as this has been back and forth I need help and I need my money back
