Defective settee

I purchased a settee from Russells Tongaat over a year ago.Within a short space of time it was obvious that the settee had a workmanship defect and it was uplifted by their head office and i then chose another that seemed as a suitable replacement although i had to pay more. It seems that every settee we bought has a problem.The stitching was loosening and this was promptly reported to the Tongaat branch where i made the purchase.This was about 3months ago. To date Russells head office has made no effort to contact us.We would like them to uplift the entire settee and provide us with a credit that we can utilize to purchase a bed.We are still waiting.This is very poor customer service.
