STILL no response after 4months for wrong material

In November 2015, an expensive wedding dress was purchased from Bride & Co in Umhlanga . and alterations were made. We were told that the off-cuts would be returned to us. In January 2016, we called to collect the rest of the material but were told that it had been misplaced. After asking for compensation, we were told that it had been found and we could collect it. We sent our company driver to collect it and after inspection, we saw that the material given to us was a cheap material, and not the expensive chiffon and dress material from the actual dress. We sent photos of this and we asked for the correct material or compensation for the lost material. After many emails and calls and stories, we were told that this problem was handed over to the operations manager and a resolve would be made. It is now April and I call or email every second day and I have absolutely no response whatsoever. This is a well known wedding dress shop and should NOT treat customers like this. Alot of money was spent at their store, and they need to look after their customers, not ignore them. Hopefully they see this and maybe someone will respond!!!
