bad service and theft

<p>I took my PlayStation 3 500 gig for repaurs as the motherboard was burnt and there repair centre early bird were unable to repair the playstation. Today I picked it up to find out the hard drive is missing. My receipt shows its a 500 gig yet I found my PlayStation empty with no hard drive . I need my hard drive after 2 years of collecting and I specifically requested hey don't touch my hard drive. </p>
