Sprint review: pay as you go

I purchase the Iphone 4 on 10/11/13 on a pay as you go plan at 2110 Henderson Mill Rd STE 22A. I recently order two iphone online thru sprint online orders. The two iphones was on back order. I had 14 days to return the pay as you go phone back to sprint. I walk into the store and Steve (manager) didn’t greet me his first words was did you buy the phone from us and who did you purchase the phone from.
Steve was so busy on the store display phones searching the web and Ben was very rude and stated that I need to contact American Express to get a refund back! I left the phone and state sure I will contact American Express regarding my refund. The store currently has the Iphone. I have not receive a refund in the amount of $106.99 I do understand it’s a $35.00 restock fee.
