Faulty mattress & unbothered store manager-House & Home Edenvale

I bought a Greencoil bed from h&h in Edenvale a few years ago. It came with a 10 year standard warranty. A few years down the line, the mattress has a hollow in the centre. I went back to Edenvale H&H with my statement as proof of purchase. The Store manager advised me that they cannot find my purchase details because my records have been archived & they cannot find them. He proceeded to tell me that I must produce the delivery note from all those years ago as proof because my statement does not suffice.

I am unhappy & feel this is all delay tactics because why is H&H faulty record keeping my problem.

I emailed their customer care & got an-automated message with no follow up. I have tried several times to call their customer care line with zero help.

This is such a pain because they were not helpful & showed no desire to help.
