Telkom keeps on billing my account after month to month cancelled!

in 2018 we took out a month to month fibre contract with Telkom. When we initially signed up, we asked all the questions, and the sales consultant advised us that month to month, if you don't pay you don't have internet. Not that our internet worked most of the time. In June/July we phoned the call centre to ask the procedure as we decided to move to another service provider. We were told that if we do not pay it is as good as cancelled due to it being a month to month. We have now app**** for a small bond, and cannot get it approved due to telkom showing in arrears. This is very unprofessional and pathetic as we are now struggling to get this sorted. I have phoned the call center again today and was told that i have to keep on phoning until i get a consultant in an area that is not affected by loadshedding so that they can go into our account. I need this corrected as this has caused many problems, why give people the option of month to month if they are just going to keep on billing you?
