I've just finished dealing with Cingular Wireless almost 2 months after trying their service. One reason I tried it out (switching from Sprint) was because they offered me a "Risk Free 30 Day Trial." I took this Motorola phone home with me that night and it wouldn't work in my apartment. I tried to return it the next day and switch my number to Verizon (which does work beautifully!). It takes a day or two to "port" the numbers so I missed Cingular's 3-day window to return. They couldn't transfer the number quickly enough so I was charged the activation fee. A couple days later, after talking several times with Cingular and Verizon reps, I got my Verizon phone sending and receiving calls and returned the Cingular phone.I received my second bill last week because Cingular didn't think I returned my phone. 30 minutes at the store I got the phone today cleared up that problem (good thing my work is flexible) and I was told I still owe $61.It appears I am paying prorated charges for the calls I made for those 6 days of service, plus all applicable taxes to every municipality in the area, and for the activation, which enabled my phone to work practically nowhere.Cingular's "Risk Free 30-day Trial" is costing me $61. That's not risk free to me - if you have a 30 day trial, and you say I can return and get a refund, REFUND ALL THE STINKIN MONEY - NOT JUST PART OF IT!Worst service ever - go to Verizon, where the phones work and the business isn't garbage.
