*********** sales team

I know that my contract is almost up to be renewed and I do keep a track of the contract and I keep getting calls from Cell C and this is starting to get ridiculous. I have told the sales team from Cell C that I'm waiting for a specific phone to be launched and I have even spoken to a manager to get my name removed from people that needs to be phoned to be given an offer to upgrade the contract and still I get phoned. Now I need to find out how many *********** people are working at Cell C as at this point I'm going to be porting my number to another provider as the harassment is going to a new level at the moment. The phone calls have gotten less and I'm not getting 3 calls a day any more from Cell C, however I'm still getting calls and this needs to stop ASAP. What can people that work for Cell C not understand when a person says no the answer will still stay no in a weeks time. Stop harassing your clients
