Restonic matres is still under warranty

I have bought a Restonic matress from Lewis store in Knysna two years ago. The matress is still under warranty. I have e-mailed Lewis headoffice. A very sarcastic and rude woman had phoned me back. After that Daniel from the Knysna store phoned me. He told me I had to pay about R800 to R900 and then Restonic will come and replace my matress. He said he will phone me back the same day to confirm the amount I had to pay. He didn't phone me back. The next morning I drove from Plettenberg Bay to Knysna to see Daniel. First he wasn't in the store. I had to wait for about a half an hour. I told him I am here to pay the said amount so that Restonic can replace it. He then fax my proof of purchase to Restonic. He then told me, he will phone me the next day to tell me how much I need to pay. He also said that he will come personally to Plettenberg Bay to fetch the money, because I told him I will not come to Knysna again and that I will rather do an ETF. Needles to say he didn't phone back. After two days my wife poned him and still no response from him. I have send several e-mails to Lewis headoffice as well as to Restonic without any success. I have even included phtos of the matress.
