Horrible signal and Service after being a client for almost 10 years

I am experiencing signal problems now for a very long while. I can't believe it and then I call the call centre just to ask what is going on and the lady said to me that I am the only one to report it with an attitude and that I could call technical support. I asked her if it is possible to change my number to a vodacom number she said yes but the bad service and very unprofessional staff in Cell C customer service I am going after I think about 10 years being with you guys I am saying good bye.
