I signed a 2-year tab plan with Koodo early this January and started a Tab with an initial tab balance of $360. Because I exchanged the phone twice (same model) in January, somehow, I got some tab credits/ adjustments and I still haven't paid any tabs for the first month. However, I already paid taxes for 3 tab charges. Right now my tab balance is still $360, which I still have to pay tax on next month. How does this work? I got the tab charge credits, but I still need to pay taxes for tab charges? This seems really unfair. I am very confused.
