month to month contract ****

I took out a contract sim only deal month to month in June last year telephonically. I was explained that if I don't pay for the deal it will be cancelled and I don't have to give notice if I want to cancel it. after missing 1 month of payment, the sim card was suspended by Telkom and I was told I wont access it until I can pay for that month as I've used the benefits for that month already which I don't have a problem with. now the sim is still suspended and I'm told that for the last 5 months it was suspended ill still have to pay for the sim a full amount cos the benefits were still uploaded even though i couldnt use them cos the sim was suspended by telkom. i dont understand the logic behind this, why would they load the sim with benefits whilst they locked me out of using them and still expect me to pay a full amount for something I don't have access to? I've since spoken to over 5 people in 2 months now they both still refuse to cancel the contract and they still continue to bill me for benefits I have no access to. I've requested to get the recording of the call and I'm told I must get a lawyer first. I don't understand! this was never explained to me when I took a month contract telephonically. they have all promised that their team leaders will call me but no one has contacted me since, its over 5 months now. they cant escalate the call cos its "not allowed". wow
