terrible experiance with cell c

I have a mobile contract with cell c and from the get go the service from them was terrible...firstly when i ordered the phone on facebook the price was about R250 or so if i can remember correctly however when they debited R299 for the phone which i inquired they advised that that is what the price was...i got over that.Then i was introduced to the Miassist service which it was also a very bad experience for a frist timer using it for my toilet which i had to force them to assist me,Also got over that then was introduced to Get more service which they said it will be active effectively but that was not it...the lady told me i have to pay my first premium before using it..That is when i decided to cancel both of the last month (October) which they gave me the 30 days period and they will cancel them which when my November bill came through they were still on my Premium which doesn't make sense since when you cancel your insurance then they advised they will also cancel the debit orders...but they still put it on my bill.called around the 15th of November @Get more service retention since i cannot ****en get through to Miassist to ask as to why the 2 service that i cancelled 30 days ago before my debit order date are still on my bill and i spoke to Penelope Choolo who was very sarcastic and making me feel like i'm stupid while asking relevant questions like i'm some uneducated person,she sent me the terms and conditions which also stated if you cancel any service then your debit orders will be cancelled also which i don't think she saw that one since she was concentrating on the (30days waiting period) now she can't even reply to my emails when i asked to be explained on the terms and conditions.....truly Cell C i am not Happy with any of your services and would like someone to call me back especially Miassist line since they can't answer their client's phone...i need to check if all this services are cancelled and i'm left with the phone contract and the mobile insurance...Kaak service you guys have.
