Mobile Q

I took my cell phone to Mobile Q in *** to have a cracked screen repaired. When the phone was returned to me, the cracked screen had been fixed, however, the LED screen now had a black line that ran from the top to the bottom, which wasn't there before. I was told that a part would need to be ordered to fix this issue and to return with the phone when the part had arrived. I returned the phone, as instructed, and they once again took my phone for repair. When I got the phone back the second time, the phone seemed to be repaired. Later that day, I tried to use the face detection feature to unlock the phone, but it would not work. I then tried using the camera in one of my apps and found that the image is black and white only and very fuzzy and distorted.
I immediately called the store to report this latest issue and was asked to return to the store the following day. Once again, I left my phone with them, but a few hours later was told that they would need to order a part and that I should return to pick up my phone until the part was available, which I did. Approximately a week later I returned the phone to the store for repair. They had the phone for several days and let me know that they were having some difficulties with the repair and had sent the phone to a third party repair service. A few days later I contacted them to get an update on the repair status and was informed that they are unable to fix the phone and that I could come and pick it up and they would refund me the cost of the original repair ($190.40). I did not agree to this offer. Instead, I told him he would either have to replace my phone with a new phone, since my phone was only about six months old, or he would have to pay out the balancing owing on my cell phone plan so that I could purchase a new phone through my cell phone provider. At the time, the balance of my cell phone plan was $721.79. He agreed to do whichever option was least expensive for him.
I returned to the store later that day with a printout of my cell phone plan expecting to either receive a new phone or a payment to pay off my cell phone plan. When I arrived at the store, he informed me that he might have the opportunity to get a replacement phone, but did not have one in the store. He asked me to give him some time to source this phone and he would contact me when he had found one. *** He immediately sent me a text which confirmed our agreement.
The next day he texted me to say that he had located a replacement phone and offered to either give me the phone or $600 in lieu of the phone. I replied that I was not interested in the monetary offer and told him that I would require assurance that the phone was new and had its original packaging. At this time, he admitted that the phone he was offering is refurbished. I replied that I would not accept a refurbished phone and again reiterated that I expected him to either provide me with a new phone or the full value of my phone plan.
Contrary to our original agreement, he is remaining firm that he will only provide me with either a refurbished phone or $600; neither option is acceptable to me.
At this point, I have a broken phone and am out-of-pocket the cost of the original repair. The person I have been dealing with, whose name is Anas, has identified himself as the owner of this branch of Mobile Q. He has since stopped responding to my texts.
