Has Anyone Renegotiated Twice?

About 18 months ago, I cancelled my contract as the prices were going up. A few days later, the calls started. First from India or wherever and then the more times I said "no" eventually to the UK where someone offered me a very good deal.

Recently, they announced the prices were going up again so I cancelled. However, I haven't had any calls from them.

Does this only work once or should I expect more calls as the cancellation date draws closer?
