Just thought I would update you all:
Spoke to the supplier today and they have made me a full winch and bumper replacement offer of a an 8274 and high mount Defender bumper all in for £1000 (I paid about £700 for the defective winch and bumper). Originally they wanted £1175 and seemed like they would stick to their guns, but theyve dropped the VAT for the hassle of me having to return the winch twice and the bent bumper, and of course my dissatisfaction with the product...
I have taken them up on the offer and thanked them for doing me such a good deal, once the deal is done I will name the supplier on here for their good service in helping to resolve this issue...
All in all, lesson learned (dont buy imported Chinese carp!), I normally do lots of research on the net prior to purchasing anything, but this time I just went for something without looking into it..
Thanks for all your help, much appreciated
Jamie
