I went to Best Buy in Alberta on Dec 22 to shop for new cell service provider with my own unlock device. I switched to Koodo because of a $10 promotion discount for 6 months on the $35 Unlimited Canada Wide talk plan, which means $25/month for first 6 months. After signed on the Koodo Self Service, I don't see the $10 discount on my account. Any ideas why? Appreciate for your help.
