I brought my daughter's LG G3 today to the Cellphone Doctor to have the SIM card reader replaced. I broke the SIM card reader when I switched the SIM cards. When I came to pick up the phone, I was told that all the data from the phone had been erased because they couldn't boot the phone after installing the new SIM card reader on the phone. I was told only after all of this had happened. And I had to pay for the full service fee even after invaluable memories in the phone are lost forever.
