Family noble walmart Bought walmart family pre paid phone.  Internet

Charged it up lace SIM card that I had bought with phone. Phone did not work took back Nextel day got full refund. Month and a half later get bill 25.19 I must pay. Called phone number to explain and oh I need the blanking phone number. Never had one went back with phone. T noble can not help and you can not speak to anyone. If this goes on my credit report I assure you that the snow fakes in California will be sued. They need to correct this at once. Why would I owe for pre paid month to month.
