just frustrated

I took out a month to month contract with Telkom. I was told I may cancel this contract within a month. I then cancelled my contract at the end of June effective 30 July. I was billed on 1 August 2020. I was of the assumption that i pay this account in advance. so I reversed the payment of 1 August which was for the payment up until July 2020 (I was just told that today). I was then again billed 1 September for 2 months as apparently an account can not be cancelled if the account is suspended. so i have no access to the data for 2 months and it is not carried forward which is I understand as it is my error for getting the account into arrears by reversing the payment. So effective i am paying for July and August for the account to finally be suspended. which I think is unfair practice. So I just want to alert people to the fact that Telkom month to month cannot really be cancelled. and if your account is suspended you don't get data and data is also not carried over when you do pay....
