Special that will cost you money

I purchased a phone from wal mart 02 01 2013 for $275 and a card for 45 plus 911 fees. I activated it a few days later after reading the owners manual.The phone started acting up the 11th so I took it back the store was sold out so they gave me a refund on the ph only and they called another wall mart to have them hold me a ph , after a hour each way I was home with my new ph I tried to activate it and you wanted me to buy another $45 card plus change my number so I will just stay with Verizon since I ordered a screen proctor$10 and a case $45 so I lost $100 plus probably $40 in gas what a company you run sincerely
