Customer service

We bought a fridge around September and October 2019, the fridge is not working so we wanted to book it inn for repairs ar the fair price where we had boughy it UNFORTUNATLEY we lost the slip but because we bought the fridge by card we thoughy maybe they would be able to trace the sale like any other furniture shops. but we were dismissed when we got there and were told there was nothing they could do to help us. Even worse we called the customer care line and spoke to Mohamed who waa very rude and not patient to even hear our request. My question is which store im 2020 does not have track of their sales??? they dont even try to check with our card number or put in any effort.... is this the kind of service they offer us?
