Dispute Over Bulk Discount Charge After Phone Payoff

The idea that I would be charged to pay for the difference between Telus bulk discount on the phones and the retail price after over 360 months as a Telus customer is silly. Why silly? Telus is treating me like a johnny come lately customer one that would take the phones and move on to another service provider. Since I am recently unemployed I elected to pay off the phones to reduce my family monthly costs. I recognize that it is in my contract. I had not planned for the massive bill created by paying off this discounted rate.  After 360 months I thought my continued customer value was worthy of being negated by this cash grab of paying off this discounted rate.  Just tell me I am not a valued customer and that you won't refund this cash grab! If I don't get the refund in the next 5 business days I will seek out a new service provider. We are no longer on contracts with Telus.
