ridiculous service

cellc is ********. two years ago I took out a lte contract with them for a monthly amount of R100 for 20gs 15gs night and 5gs day. my contract was suppose to end on the 8th of May 2018. I called in March to give them 30days notice as I was told to do so by the consultant at the cell c store at ********** upon calling the call center they advised that it will be cancelled. I then called in April to confirm th a it will be cancelled the lady dasiree said that no cancellation was done and that she has put in a request for a investigation and that she will get back to me with the findings but no one called. I then tried calling for a month where end of May I had to go in to the store and there after spoke to a lady Michael where she send the request again and said she will investigate and call me in two days but no one has called. cell c has not cancelled my contract and I signed a 24month contract not a longer one and they are debiting more then what I signedon for and giving less data.the 26th of May they devidebited R174 and gave me 10gs data now on the 26th June they debited R200 and gave me 10gs data 5gs day and 5gs night. they are ridiculous. every time I call for them to sort this out and refund me they give me the run around. if there Employees does not know how to do there jobs and cancel contracts when requested why does it become my problem. stop ******** us out of our money and train and hire adequate people.
