Bad service

I wish you could give this 0 stars. I brought in my device for repairs in January I didn't receive it last month they downgraded my device without concern and I didn't want it the lady at the register tried to persuade me to take something I was not happy with I got all these messages on my phone telling me that my device is being fixed but they just exchanged it for a very bad phone I am depressed I still get the repair messages on my phone but I got a call saying they bought the right phone! I want my information on the phone, not a new phone. I've been waiting almost 70 days with no updates on where it is or when I'm going to get it.
