Samsung is the worst service ever gone through ...they do not have the technician s name in their records they send to the customer ...secondly they do not trust the customer ...they trust their technician ...even if they spoil the product temper the product they blame the customer for calling the outside engineer and done it ...they do not have talk properly to the customer they block the number as well their compressor warrenty they give for ten yrs ..but at time when u need to change compressor they give lots and lots of excuses and ur barred from the Samsung u won't get a call neither the service instead u have to call outside engineer to do one ..u r not left with any other option ...so guys pls don't go for the Samsung products ...if u don't want to face the problem as I did ...
