Grafton should provide customer service for their products

We bought a Grafton Everest lounge suite from Rochester, Clear Water Mall. It was delivered on 24 September, 2020. It has not been scotch guarded (I got not certificate on delivery) and it has stitching which has come loose. I have tried getting assistance from Rochester, the branch as well as head office but to no avail. So I contacted Grafton for assistance, also to no avail. I am really, really upset that my expensive lounge suite will just get dirty and fall apart!
