Telkom SIM only Month to Month Contract are a ****

I took a month to month data contract with these guys, for 3 month I did not use their services and assumed that if I don't use the service then I wouldn't have to pay for the months that the services. The contract clearly said it was month to month and it was a SIM only deal. With these guys they bill you and expect you to pay even though you don't use the service. The worse part is that they have no option of stopping the account from accumulating. They want you to first pay for all the months you missed before they cancel even though the account was inactive for those months.
