I have been with Sprint/ Nextel for 6+ years. Dropped calls all the time, also my bill was different every month, always higher. I was charged for text messages and never sent or received any. I finally called to cancel my contract. I was told that I had to pay an extra month plus the$200 termination fee. I ended up paying over$360 just to get out of the contract.
The first time they gave me the phone for free and a$300 credit. They have the very poor customer service until you decide to cancel with them. Every time I called in for customer support I would get transferred several time because there operators are poorly trained. Never buy you phone from a Sprint store. Majority of the stores are owned by Sprint.
