no choice when dealing with a bully

i received a call from a agent of elite mobile at 11 o clock. i informed the agent to call me in an hours time as i was at work and unable to talk. He called back after 12 as i requested. my disappointment lies in the fact that he tried to force a product onto me that i had not agreed to purchase. i informed him that i wanted to first physically go see the product in a vodacom store. his condescending attitude and aggression has left me feeling cheated of my right as a customer. To try and force a product on me that I've never heard of and become aggressive when i try and get as much information on it, is a sign of poor quality customer service. allow a customer the right to make an informed decision without being bul**** into accepting a deal.
