Hmmmm
prove it's yours and i can tell you ;-)
Sadly this is the day and age we live in, and these questions are asked on a daily basis by hundreds of petty thieves needing to sort this issue to then sell on their goods (nothing implied)
You will need to come to expect to be asked for proof of ownership before any technician or store will be keen to help you with this type of problem i'm afraid
