I would never purchase hisense again

So we purchased a fridge a washing machine and a tv...and the fridge is giving us some problems... So i called in to find out about the warranty as I know hisense gives you 4 or 5 years... I registered all the appliances that I purchased... But for some odd reason when I called they said they have no documentation of my registration for the fridge... I submitted everything 4 years ago... But now they have nothing... So that's the warranty... You register and then when you actually need the help they give you stories.... And ask for the store slip... 4 years... Really now...
