I noticed on my past two bills that even though I actually paid two different totals that I was changed the exact same sales tax each time. I thought this HAD to be a mistake, since when you pay tax you pay based on the actual amount you PAY not on what something costs BEFORE the total has been calulated. I called CS. The rep tried to tell me that I have to pay the tax based on the pre discount total. This clearly sounds wrong. Can anyone point me to where it states in the contract that you pay any tax based on PRE totals not the actual BILLED total. Seems the CSR can't answer the question.
