SAMSUNG LIE & WONT TAKE RESPONSIBILITY

took laptop 2 samsung (WANTED ORIGINAL PART) to fix broken screen mid Feb/15. told to leave laptop 2 check part availability & will then quote. 18/2/15 received quote & I accepted. Told will take day or 2 but not so. No reply 4 days I followed up & was told they were having minor problems only to discover they were actually trying 2 use a makeshift part (not original) which I now only found out once computer was opened. Having already opened laptop I just ignored its discrete effort in trying to take a short cut (not original part) bcause I needed my laptop & info thereon. Again days later 17/2/15 I was told specialist was coming to assist & will call me when finished but again did not call so 2/3/15 I called & was told pc is working & just needed to b put back 2gether & ready next day. 3/3/2015 received sms 2 fetch laptop (no explanation or alternative) unrepaired. I have proof of lies. SAMSUNG MUST TAKE RESPONSIBILITY 4 OPENING MY PC & TRYING 2 USE WRONG PART WITHOUT MY CONSENT. I WANT MY PC FIXED AS SAMSUNG TOLD ME IT WAS... OR ELSE AS IT WAS WHEN GIVEN IN (NEVER HAVE BEEN OPENED). NEVER BYE SAMSUNG it cant support it's own products. my laptop is only 5 yrs old.
