Disgusting customer service

I canceled my contract with Supersonic in February, March being my cancelation month, account was paid up to date, but they still billed me a few months after. I have queried an outstanding amount on my account since April, spoke to numerous of staff in Finance, sent numerous emails, head if finance assured me account would be sorted out and I need not worry about having my services suspended as they would sort out my account. Out of the R307 that should have been credited they credited me with R46.33. Sunday my services got suspended, i called the customer service and explained the situation that account hadn't been sorted by Finance department - Lesego and Tebogo from customer services just said they can't help me as Finance only works Monday to Friday, I asked them to then switch my services back on until Monday morning as to when Finance is able to confirm the query, they just said they can't switch my services on.
