Sales call from Mohammad at MTN

I received a call from Mohammad at MTN at around 9:57 this morning stating that my number has been selected in a promotion for a new Hi-sense handset... this man is so damn rude... he did not even give me the opportunity to finish my sentence... just started saying thank you and hung up... you expect to get more customers at MTN yet such a bad attitude towards potential customers... what is your expectation? I am in the contact center industry... do you need someone to teach your staff some courtesy and manners??? I have had enough of such bad attitude and lack of manners
