Cell C - Bad service

Everytime I have to sort out anything with cellc, I have to call in at least 4 times before someone helps me in a way I feel I have been helped, each time I get different answers to the same basic questions, I have wasted so much of my time on that alone. When I cancelled one of my contracts, I had to again call in a few times before I was helped to get the cancelation completed, I paid the amount I was told would cancel the whole contract, to my surprise I saw on my cellc app that they are planning to debit R2300 off my account at the end of march & my contracts that is still active is only supposed to be R600 p/m. I called in on Friday the 13th of March 3 times, each consultant had a different story & reason, one of them told me they can not assist me with payment arrangements as this is not an arrears amount. This morning (Monday the 16th of March) they told me that because I paid the cancelation fee they did not debit the money for January & February from my account, what frustrates me the most is that I was not made aware of this at all, I did not know that they will not be doing the debit orders as per normal. They did not give me the necessary information & now I am sitting with this big amount that I need to pay, money that I do not really have. I am truelly unhappy with the service from cell c & I am literally a walking stress ball at the moment.
