Cell C - no customer care

For years I've struggled with network coverage. After several sim card exchanges the service is still not reliable. I've been trying to end my contracts with Cell C since January when my contract reached its expiry time. After several calls in Feb and March I had to hear the news yesterday that the notice period was not even registered in January. In store as well as customer care can not resolve this for me.... Unexceptional. At the end the customer is struggling and paying more on out of bundle fees.
