I had a mixed experience with Wind as well. They tried to pull the same thing on me. I gave up my number and told them I was ending my contract because I was leaving the province. (I was) It was a 1/2 hour call with the customer retention department before they let me go. Painful.

We also had issues buying my Wife's phone though different Wind locations. It turns out they are all franchises and not all are official wind stores. The unofficial ones rip you off by selling you things that are normally included with the activation of your phone... or charging you to activate the phone period (which can be done online for free.) They tried to charge us 50$ to activate and another $50 for a sim card! I went up one side of him and down the other and went to an official wind location. Night and day difference. I would not go wind again, even though it was the cheapest option at the time.
