Metro PCS Scam, Lied, etc West Allis Wisconsin

I've been with Sprint for 10+ years and decided to leave them to go to Metro PCS because they advertised half off your sprint bill if you join. Well the 2 unprofessional sales people there sold me the K7 which she said was an excellent phone and had an excellent camera. Coming from an iphone to a K7. I told her the camera HAD to be great and she insisted it was. IT is terrible! So I got sold a phone that sucks. That is #1. #2 I sure did NOT get 1/2 off my sprint bill. She told me the only plan I could get was a $40 plan. That the signs located in the store about the Sprint bill were not true and I had to go with this plan. so #2 LIED. #3 she then told me that I had to purchase 2 accessories so she could apply all the discounts to my plan. So when I left there i ended up spending about $160. I feel scammed in all ways here. Advertising very misleading and poor poor customer service. And some how I can not get my money back or get an upgrade. Not even a credit for everything i dealt with!
