Alpine Leather lounge suite - Bad product or bad after sales service?

I bought a leather lounge suite Sept 2022 and now the foot rest is flaking off. House and Home, where I bought it, try to assist but according to Alpine, I have used a product on the suite. They do not reply on my request to contact me and come and have a look at the suite, they just ignore me. If I have used something on the suite, the other parts of the set would have shown the same problem? To be expected, they've got their money and I am R40 000.00 down the drain because of very poor after sales service, or maybe it is a poor product, but again for that amount of money, you will expect quality.
