I dropped my phone and the top right has a small crack. then couple days later I tried charging it and it wouldn't charge. and then I took it to the store where I bought the phone and asked them why my phone won't charge. they took a look at it and told me my charging port broke. then they gave me a address and phone number for the onsite cell repair in Houston, TX. I tried calling them but I didn't get an answer. what do I do?
