Billing and cancellation

This by far is the most ****test service provider ever, I was contacted by an agent ,whom offered me a data contract which the first month I understood it’s prorated charged ,I asked if it’s a month to month contract he then agreed and I asked him again he agreed, December and January they never deducted so I had to do a manual payment and when I asked why cause I got funds in my account they then told me that since it’s holidays Telkom debits before initial payment date, then February the account was suspended and yet I did my payment which I did not understand,I just went into a branch asked what’s going on a lady said to me “your line was suspended cause you owing ,how am I owing if I did not receive any data ,line is suspend and now I got a sms saying they going to take legal action, yet I advised them I want that contract to be cancelled since it’s a month to month , which they did not and still I’m getting calls from Telkom stating I owe them R1259 which I keep asking what’s that amount for cause the line has been suspended data is not being loaded ,Telkom is just a **** service provider, how can I pay for something im not getting ,I just want this **** contract to be cancelled under my name !!
