I purchased my Macbook back in 2010 with a four year warranty expected to expire in Sept 2014. A couple of days before expiry I thought I'd bring in my macbook for a final check to make sure everything was working adequately which to my knowledge I new there was an issue w/ the battery. The associate who assisted me in a manner of dis-interest and seemed to give me cold one-word answers or short-form answers to the questions I had regarding my warranty asked me,"Is it okay if we delete everything off of the computer?" I responded, only if he had to but I would prefer they not because I needed many of the info saved on there. He said to me that they would have to and when I asked him about the "Backup" line one the service application sheet in which he wrote, "no" I told him, "I see here that you have a choice to back up the info on the computer, so I would rather you change that no to a yes" and he said that they didnt have a choice to do so. It was also explained to me that it would take 5-10 business days to have my macbook checked, diagnosed, fixed, and returned back to me. This was FALSE. It took 2 weeks and 2 days to get it back and after the first week was when I got a call on what would be covered under my warranty and what was not and would then incurr additional fees (key word:"estimated" at $250) I refused the additional fixes and just asked that they fix my computer asap as I desparately needed it for school and was falling behind. He was unable to give me a ststus update on the services being done to the computer and its arrival time. Upon retrieving my macbook, EVERYTHING was deleted. Including my Microsoft office that I had paid over $200 for back in 2010 and could not find the original disc used to re-download it. I lost imperative information due to this service loss and now am experiencing a lot of difficulty in moving on in certain prior obligations and responsibilities. Pretty much I felt the backup could have be done since it was an option of yes or no, in which the asssociate wrote no. and they could have did their due dillengence in the part of excellent customer service by thoroughly explaining what pieces of info and/ or softwware would be deleted, as someone who is not that tech savvy, it had completely slipped my mind that microsoft word was not apart of the apple softwares and would therefore not remain. I spent more money and wasted plenty of time due to their laziness and time discrepancies. Best buy does not even offer and option to purchase extended warranty which is crazy for a computer that is suppose to apparently last my a lifetime..And what was worse was when I was asked to fill out a survey to review my latest service experience. The first question asked me if I had recently received service from a best buy location I was unaware of or never heard of and different from the location (dufferin-wilson) I had originally went in for my service; so I answered I don't know (because I didnt know where they shipped my computer to for repair, and yes I was informed that the repair would be done at another location that supplies mac parts). Following my Input the survey ended. I was unable to give my interpretation of my last service for whatever reason. I am incredibly upset with the negligence of the Geek Squad at Best Buy and hope that this review will encourage more training and development for the employees in regard to customer service as well as efficiency improvements on work practices and knowledge of services. Best buy needs to offer useful perks for its consumer, more specifically extended warranty, that way I could have waited for a break at school to hand in my macbook instead of falling behind classes because I was lied to about how long it would take to receive my macbook back.
