Hi I work at walmart too and enjoy the 30% discount, you should approach the osl associate, the person that set up the plan for you, just give him/her your WIN number and should be good to go. 

I was charged the same thing, but was able to get bill credit with the help of fido rep via twitter chat. It won't be hard.

You should approach the OSL or people from electronics, they will set it up for you, they will just need your WIN number and you're good to go.
