UNFAIR TREATMENT

Since I have cancelled my *** month to month "contract" and paid R457 at the *** store and returned the wifi set, what is that I am being billed for? When I applied for the wifi, I was told it's not a contract, it is a month to month, and if I dont pay I will never get credited with data. It happened exactly like that, I did not pay and I was never given data for that month, to my surprise I got billed at the end of the month, I never used the data. I then paid at the store and returned the set and subsequently cancelled the so-called month to month contract. can I get a breakdown of what am I being billed for since I cancelled the "subscription". What is R1334.00 for? Can I get a record of the call when I applied for the deal?
