Hi guys...so like 10 months ago I bought a phone from Koodo...I paid the FULL PRICE but now I want to get their blackberry. Its on sale now but I dont know if I can use the 50$ I have on the "positive tab" to get it for free. Im so confused...any help!

*Since I paid my current phone with my own money, I could leave Koodo whenever I want to without having to pay...right?
