Poor sales ethics

I was contacted by a man , i believe his name was Leon, that is what my true caller shows atleast.

This guy was rude and pushy, and engaged in what i consider bad business ethics, i was phoned because i already own a timeshare week at baywater village, he firstly tried to devalue the product i already have, by trying to convince me its an unpopular resort , and i quote " a slow town" where its located, now he initially tried to offer me a week in crystal springs as exchange which is worth alot less than mine, firstly thats a slow town ! Pilgrems rest ! So he either doesnt know the resorts and their locations, or he blatantly tried to lie to me, and i believe it is the latter actually, because he tried to convince me that my premium is subject to a 30% escalation anually, but he will do me a favour and only make it 7%, now i read my contract , that is a blatant lie, i even confirmed with my broker to confirm that its not a favour he can do me, the escalation is only 7% period! Yet he tried to argue the point non the less, and then after he tried to argue the benefits i receive when exchanging the weeks, asif i dont know what my exchange benefits are, and what is stated in my contract, and confirmed again by my broker, that i can contact on his cell personally. Which again by the way after arguing with him had my broker email through to me again to confirm my suspisions that this guy only tries to sell on lies and deception. He initially told me he cant keep a week that i might be interested in, until he heard that i do have a credit card, after asking me bluntly, then all of a sudden its fine to keep it and talk later again, so clearly its all about the money and customer service and satisfaction take a clear back seat ! I work in the sales industry myself and the basic rules apply when dealing with customers, always be honest and transparent, polite and never ever devalue an excisting product or service the client already has by an affiliate of your company !!! This man i feel will bring the company and its affiliates into disrepute, he left a very sour taste with regards to QVC an affiliate of LPA
