Metropcs metropcs would not exchange faulty lgk7 phone. Raleigh North Carolina

On May 13, 2016 I took my cell phone a model lgk7(MS330) to a MetroPcs in knightdale North carolina on hwy 64 because it locked up on me.On that day store manager Stephanie Jarret couldn't get the phone to work, she told me to call her or come back on the 17th. She kept the phone that day.

I went back 4 days later on the 17th of may to the same location I went to on May 13,2016 I was handed the faulty phone wrapped in a claim ticket and was told to go to the 3110 New Bern Ave store for the replacement. There stephanie Jarret produced another lgk7 phone, this time she took the sim card and battery from the faulty phone and used them for the new phone. I was told the company uses the battery that came with the faulty phone and that the company would of known if the battery was faulty or not.

The new phone that she received was not working, the touch screen did not work.Stephanie handed me the back cover,sim card and battery of faulty phone and told me to call her or check back in two days.

I went back on the 19th of May and was told she hadn't received another replacement phone.

I went back to the 3110 New Bern Ave metropcs location on 5/23/2016 at 9am with backcover,sim card and battery of faulty phone, an assistant manager was working that day.I was told that Stephanie Jarret  said I kept the faulty phone and that they couldn't give me a replacement until they received the whole phone. I informed the assistant manager that stephanie  kept the phone, but only gave me back the back cover, sim card and battery.
