I brought an Iphone in for repair. I was given an estimate, and the cost of the replacement part was much higher than the cost to purchase the same part elsewhere. I called back and asked whether, if I bought the phone back with the part I needed, Desktop Solutions would honor the labor quote. I was told yes. I ordered the part I needed and when it came in I dropped by to see if I could have it installed. I was told that the tech was out on a service call, but that if I would bring the phone by the next morning it would be repaired. I had the phone sent to Desktop Solutions with the replacement part and the original quote the following morning. I received a call from the tech who fairly rudely explained to me that: (1) he couldn't work on my phone until I scheduled an appointment in advance; (2) he would not install any parts in the phone that did not come directly from Apple; and (3) that Desktop Solutions marks up its replacement parts and he would not honor the original labor quote. I responded that his partner had instructed me to bring the phone by that morning - to which the tech responded that he had not been told that I had an appointment and therefore I needed to make a new appointment. Next, I reminded the tech that I had specifically asked if he would honor the labor quote if I sent in the part I needed and he had told me "yes." The response I got was essentially "sorry." I also asked whether the part I sent over would be installed if I paid more for labor. I was then told "yes," but that the labor would be much higher (over double the original quote). When I asked why the labor was so high, instead of an explanation, I was once again told that non-apple direct parts could not be installed so it didn't matter. Fortunately, my phone went to Oops Repair, was fixed in 15 minutes (without an appointment), for about half what Desktop Solutions tried to charge me.
