Dollar General review: deffective pre paid phone

On Sept. 29, 2013 I purchased a Net 10 phone from Dollar General. Once I got home to activate the phone I stayed on the phone for an hour to be told that there was an error on the phone and they could not activate the phone. They gave me a referral number and said to call back in 24 hours. After the 24 hours I called back to be told the same thing. This time I was on the phone for 1 1/2 hours. I ask was there something wrong with the phone. They said yes. I ask about getting a refund. That said that if I purchased it online that they could do the refund but since I purchased in the store. I would have to go back the store. I went back to the Dollar General and spoke with the manager. She said that all sales were final on pre paid phone. There was not a notice near the phones stating that. I said what do I do from here. She said I would have to go thru the Net 10 company. I called the Dollar General corporate office. After a few days the general manager called to say that to go back to the store and the store manger would help me get the phone activated. I went back on Saturday, 10-13-13 to the store. The manager did the same thing I did to get the same results. She was told to call back in 24 hours with a referral number. So on today 10-15-13 I called back again to be told that there is nothing they can do. Again telling me to go back to the store I purchased it. This is crazy! Where is the customer service. You should not give your customer a run around. What happen to good customer service. I have since gone to another company to purchase a phone. I want my money back.. Advice to anyone purchasing a pre paid from the Dollar General.. DON"T! It is a rip off to the customers.
