I took my phone to get the back if it replaced as it was shattered. I paid $150 to have the part ordered, and was told to paid another $150 after it was fixed. They ordered the part and told me they would call when it came. I brought my phone to tell them once they called and they told me to come back at the end the day and my phone would be fixed. I returned and was told that my phone was not fixed and that suddenly there was a bigger problem than the cracked back and that my phone was dangerously overheating. I was told they would need another day to take it apart and see if the problem was with the chip in my phone or if it was a faulty part. I was told to return the next day around lunch and they would have an answer. I returned and was given my phone with the old cracked back on it and still had the overheating problem. When I dropped this phone off with them the ONLY issue was the cracked back. I asked if I could get the $150 that I already paid back, because the part was not used and no service was provided. They refused and said they could only offer me $12 since i paid $12 more dollars than the part was worth. I asked to have the part instead so I could resell online. They did let me leave with the part, however I still feel as if i was scammed as I left with a phone that was more broken than before and with $150 dollars less than before I entered this store. I was never once warned that it may not be able to be fixed. I was never given any type of receipt. I was never issued an apology. I paid for a service I did not receive. This is not how a business should be run, and the worst customer service I have received at any store. I have talked with several people, who said they have been in a similar situation with this store where they paid for their phone to be fixed, and received a more broken phone and no refund. This business is a scam and should be shut down, as they can't fix phones or treat customers well at all.
