Thanks everyone for your help!
So called T-mobile and the representative this time was so nice and helpful!
She said that she couldn't do much since it was purchased in the store, but she told me to go to the store and do a return and re-purchase if they would not give me the price adjustment.
I called the manager of the store and he was also very nice and offered me the price adjustment up front!! I was only able to get $50 back because I was not eligible for the rebate since I did not purchase the data plan. So instead of paying $280 for the phone (curve 8320), I paid $230 after the upgrade fee and taxes.
Its not bad, but after researching Verizon I noticed that the Curve 8330, a newer version of the Curve, is only $100!!!
I just don't know what to do anymore. I really want to call T-mobile and ask if they will do a price-match, but I highly doubt that will happen. I would like to switch to Verizon, but the family plan is about $20 more per month than my T-mobile family plan.
Any suggestions or should I just stick with what I already have?
