Best Buy Fouled up Contact List in Smartphone San Rafael California

Completely scrambled my Contacts on my Motorola smartphone. I had returned my phone 9 times for repair and each time Geek Squad replaced with same model Motorola which only gives 1.5 to 2 hours battery life. Instead of giving me a different model refurbished phone Geek Squad kept replacing it with a model that should never have been placed on the market. The really damaging Permanent Problem the Geek Squad created for me is a clerk downloaded the Contacts to one of the many, many refurbished replacement phones anywhere from 6 to 15 times! The end and final disaster for me is that Any new phone I buy, whether from Best Buy or anywhere else will continue to download the Contacts I've established over decades anywhere from 1 to 15 times. This disaster even has bled over to my main company PC. In short our Contact List is in a state of permanent confusion. A total permanent disaster and I wonder if Anyone out there can tell me how I can get compensated for the error of the clerk?
