I have been a loyal T-mobile customer for 6 years and when upgrading my phone from a G1 to the Samsung Vibrant they increased the data price to $30/month when I previously payed $25/month. Before upgrading the phone, I spoke to a T-mobile representative on the phone and she said that if I chose to upgrade to another android phone, the price would stay the same. However, when I went to Costco to upgrade, the system required us to add the $30 service before continuing, even though I already had the $25 service. They told me I could call t-mobile and negotiate this with them. When I called T-mobile I wasn't told anything except "$30 is the new required price". If I already had a data plan, why would I have to pay more for the same one? When I previously used web-to-go on my Blackberry, I paid $5.99 (I think), and eventually they raised the web to go price to $9.99, but the price remained the same to me because that was the service I had purchased. Has anyone had a similar experience and was able to get their old data plan price returned?
