Well what a laugh I’ve just spoken to WCW in barry and I don’t think he could have been more unhelpful if they tried the first person I spoke to about the membranes cut me off the second person pretty much dismissed any idea that they could possibly be faulty and was very reluctant to get me a returns no, he did get a rtn for me but said sorry we don’t except any rtns after 14 days but I’m welcome to send them back to them anyway wouldn’t say what if anything they would do after that though
