Electrolux Undercounter geyser

I installed an Electrolux undercounter geyser. Last week the unit started leaking from the inside. I contacted the store where I purchased the unit and they contacted Electrolux. Electrolux required a POP to prove that the unit was less than 5 years old. I had a hard drive crash and could not prove the date of purchase. Electrolux refused to consider any compensation. BAD BAD BAD Beware!
