Not wishing to take sides here it seems to me you are unhappy about the offhand way you feel you were treated rather than about the actual problem with the bike.Your so wrong,I phoned up and very politely said that the handbook / tools were missing and the chain guard was damaged, at that point I was OK about it,expecting them to resolve the small problems over the phone. I was put on hold four times while the Kudos person kept going to ask questions about the problems, they were very vague with the answers, when I quoted to them that they say all bikes are delivered with handbook / instructions and toolkit, they hesitated then said oh not my bike. Why couldn't they just replace the rear part of the chain guard, its not as if it's expensive,I'm sorry but to ask for a picture to be emailed to them is a disgrace. Yes I am angry now, but I was not during the phone call,I did point out I wasn't happy with the requiring a picture,and was a bit unhappy with there after
service,wouldn't you. I will give them tomorrow to get back to me, it could be a blip,but I'm very disapointed in there lack of interest.
You seem to have started off being thoroughly reasonable and due to undoubtedly unprofessional handling of your complaint you became angry, completely understandable.
Kudos are well thought of on this forum and seem to be a very reputable company, I'm surprised they haven't posted on this thread as it only took them 12 minutes to respond to your post asking for advice as to which bike to buy!
It sounds like you have an excellent bike there and maybe take a deep breath and let them sort out your problem as I'm sure they will.
