Disrespectful Sales Agent

I received a call from a Car Track sales agent by the name of ADEEL. He is the most disrespectful sales agent this company ever employed. The more I am telling him that I am shopping around for various tracker quotes, the more he is wanting to convince me that his product is the best and if i am still shopping around then I don't really want a tracker or don't know what I am looking for.

I am the client and the final decision lies by me whether I am gonna go with his product or not. I have done my research on most of the products available to me, so I don't need him telling me about the company's track record.

I have changed my mind about ever making use of this company to keep my car safe. He can't even keep a client safe telephonically.
