Vodacom employees are rude

I was called by a telemarketer offering a contract, I politely told him I have no interest in the product, I could also clearly hear that he was reading from a script. Even though I said no and was explaining why I am saying no he just spoke right over me trying to force the product, when I told him he is being rude and interrupting me while I'm trying to work he told me in a rude manner that he is also trying to work and then put the phone down on me. This behavior is disgusting, especially since I tried to be polite in the beginning. I want you to remove my number from your system, I have 0 interest in joining Vodacom and most definitely will not ever consider it after this experience. Apart from your terrible coverage for signal, your employees are just a terrible. Absolutely disgusting
