Am I being SCAMMED?

I was told at the Owings Mills, MD store that I need to call customer service to return my Xfinity mobile phone. He said even though it had only been 12 days since the phone was purchased the computer would not allow him return the phone because the phone number had been ported out and he would be unable to reactive it to complete the return. He also stated that through customer  support,  I would also have 30 days to complete the return. I called the next day and the woman who stated she is in the Philippines tried to sell me a smart watch and then told me she didn't have time to help me further because her shift was over and she had to go take care of her father and I would need to call back.   

The weekend came so I called today. This person, also outside the country, told me multiple times it's impossible to return the phone because it's over 14 days at this point, but he's going to help me out. After several minutes on and off of "hold" he told me to go to FedEx at 7800 Eastgate Blvd, Mt. Juliette, PM and they would take my phone and know what to do with it. I told him I live in MD, and he put me in hold again and came back and said I was to ship to that address. I asked him where PM was and he said he is not in the States, so he would check. He came back and said Tennessee and I realized PM was TN. 🤦He did not give me any other information except to say he will call me in 7-10 days to refund the $35 I will have to pay to ship the phone. 

I have googled the address and this is NOT Xfinity and on other pages I have seen that a QR code is necessary to make a return. 

Can you confirm that it is safe to return the phone here and that the protocol is to receive a refund for this phone (and shipping) once it is received?  

While I'm at it, I want to make a complaint about the fact that your computer systems are set up that an agent at the store cannot reactive a phone with a random number or WHATEVER has to happen so that it can be returned! This should have been a simple return that has turned into a huge hassle and serious questions about what is going on in these overseas calling centers and conflicting information across platforms.  I know that I am not the only one with these issues, it's posted all over the Internet!
