I paid tab off when I paid August's bill - it states that my closing tab balance is $0.00. However, I was charged $15 for Tab on September's bill. My tab status is actually "No Tab". I've looked at this situation from the perspective that I must some how be wrong, but that just doesn't seem to be the case. I really want to resolve this matter... especially if it turns into a reoccurring issue. How should I go about addressing this? I would like to just call Koodo, but am concerned a fee would be involved (the customer service fees are disconcerting).
