Spam, caller ***

I had a call from +***7 at 12H38 on 27.08.2015. he said he was from Cell C, I rep**** that I would go to my local store for upgrade, he advised me that it is not regarding an upgrade that it was a product, I had to say no thanks at least 10 times before I actually hung up on him. Please remove me from all your data marketing databases as I have never given you permission to give me spam calls. it is harassment if you have to say no more than once and he still insists on continuing. REMOVE ME FROM YOUR SPAM DATABASE, if I want a Cell C product I will go to the store or the official Cell C site.
