device assessed lies at branch for 8 months now damaged and i demand replacement

PACKARD BELL LAPTOP UNDER WARANTY AND DEFECTIVE. TOOK EDGARS 4 MONTHS JUST TO BOOK THE DEVICE FOR ASSESSMENT. A MONTH LATER THE ASSESSMENT IS ONLY DONE AND AT THAT TIME THE WARANTY EXPIRED AND THE DEVICE WASN'T REPAIRED. IT WAS WITH THE CENTURY CITY BRANCH FOR 8 MONTHS BEFORE I RECEIVED IT BACK! NO EMAILS NO CONTACT WHILE IT WAS IN THEIR POSSESSION AND RETURNED TO ME WITH NO CHARGER. THEY SUPPLY ME A CHEAP KNOCK OFF CHARGER AND I SUSPECT IT BLEW THE MOTHERBOARD. NOW I HOLD EDGARS LIABLE TO REPLACE THE DEVICE AND ALSO REIMBURSE ME FOR A LAPTOP I HAD TO RENT WHILE MY DEVICE WAS GATHERING DUST IN THEIR STORE!
