Net10 Wireless review: customer service, incorrect information from representatives

Purchased cell phone on June 23, 2010. Received message on screen on May 13, 2011 to call Customer Service. Spent one hour entering codes to be told that phone is defective. On May 26, 2011 activated new phone but 1179 minutes was not transferred to new phone. Spent 4 hours on phone entering codes, being transferred to person to person, and cut off twice. This was too much I told them to cancel and was told by several reps that I could have the minutes credited to my Master Card. The last person I talked to stated that I could not get that credit. I talked to 12 people that day. I got address & phone # of corporate from them but when I called I got the same people in the country of Columbia. Looked up address & phone number online and called non toll free number and talked to American (yeh) But that person with his "don't care attitude" told me the minutes were non refundable. I told them they need to greatly improve their customer service and training.
