Riverwalk Furniture Poor Service and Substandard Quality Products

I have ordered a Designer chair but opted for Leather finish from this company in December 2017. I paid quite a substantial amount more for the Leather. Delivery should have taken place first week of Feb 2018. Company is never available by telephone line, but they claim their lines are working. Sometimes their excuse is that lines have been ******. I have not even once got hold of them in the 2,5 month period. They hardly answer emails, if they do, its very sarcastic when you complain about the poor service and the fact that you cannot get hold of them via phone. Upon questioning my order after so many weeks, they advised that it has arrived and that I should pay the difference before delivery could take place. I decided to pay the warehouse unexpected visit to view the chair before I pay the difference, only to find that the chair was damaged AND that plastic vinyl was used instead of LEATHER. I have not been able to get hold of them since my visit, nor have they answered my emails or phone calls. Anyone with more info on the owner or this company will be appreciated. Thanks Susan Prinsloo
