House & Home Refuses to Refund Me.

I am extremely dissatisfied with the customer service I received from House & Home. For the past two months I have been complaining about a Sealy Grande bed set that I purchased from them in November 2024. I only started using the bed in January 2025 and after only one week the mattress started sinking. I then went to the store and they offered me an exchange. They exchanged the mattress and I was told that it is a "newly manufactured mattress". After two weeks of use, this newly manufactured mattress also started sinking. I then complained AGAIN and this is when my horror started. I requested a refund from House & Home as I was not willing to go through several exchanges. House & Home collected the bed from my place after they told me that the bed needs to be at the store before they could refund me. The bed has now been returned to the store and they are now telling me that it will take 10 working days for them to refund me. Funny that when they take money from our accounts it's a quick process but when they need to give it back there are "processes and checks" to be done and it goes through different people. When I asked what are they checking I was told they are checking banking details and "other stuff". The lady could not explain to me what are the "other stuff" they need to check. Now my question is, if you are checking banking details, why does it need different people to check and why does it need 10 days??? I have had it with House & Home. Their customer services sickens me. Whatever you do, DO NOT PURCHASE ANYTHING FROM THEM!!!
