Query: Phone is good, service is bad!

I bought this phone back in dec 2002. It came with a rebate for $150. I filled out the forms and mailed it to Nextel, NEVER receiving the rebate! I called and they told me that there was nothing they could do. That if I called sooner they could have had me fill out another form. Well I waited so long because the form I filled out said wait a min of 12 weeks! Also they have been messing up my bill every month, charging me for minutes that should be in my plan, PLUS my plan has been changing. The phone is good however Nextel as a company is not the best.
