MetroPCS Retail Store MC4 Wireless Inc Phone was worth $49.99, charged me $165.00 had damages, refused to accept return or exchange Brooklyn New York

On August 26th I went to purchase a phone, because the one I had wasn't working well on MetroPCS, because it was a T-mobile phone. I went into MC4 Wireless a MetroPCS Retail Store to buy a MetroPCS phone. I left with an LG phone. When the store agent was fixing my phone I noticed the screen wasn't working well, but thought it's a new phone so maybe it's now. I proceeded to pay $165.00 for the phone and left. When I got home I noticed the phone acting funny but kept it to see how it would work this was on a Friday. On Sunday the phone went in and out so I called the store. The manager told me I was unable to exchange the phone and had to give it another few days before I could do that. When I told him you know what I will return the phone instead, he said did you have service with MetroPCS before buying the phone I said "yes" he said I am sorry we don't accept returns. I proceeded to tell him the phone is not even 2 days old. He hung up on me my partner called back and the person I the phone proceeded to curse him out. I called MetroPCS and they said they'd send a manager to investigate and told me they'd call me back in a few days. They never did. Someone was calling my phone and hanging up and wouldn't speak when they'd call. I also spoke to the rep on the phone and he told me that phone was going for only $49.99 on top of that the phone was broken and looked used. I fought with my bank, but they told me I used a chip to pay and that they couldn't do anything about it. This store is a store whoch is in a neighborhood where I am sure they're doing this all the time to people and some people probably don't know what to do.
