Well after sending many photos, & them claiming it was my fault, they agreed to take the bike back & inspect it. They received it back 3 weeks ago & told me it would be inspected within 48 hours, 2 weeks later

they had finally inspected it & agreed to replace the frame. Got an email whilst at work last night saying it is now complete & will be shipped back to me.
TBH I'm not right fussed about it now & think I may sell the bike on. I was never as happy with the RT80 as the RT57 & not sure I'd have confidence in the new frame. But how much is a new frame with used components worth ?
