Hi Jeff, sorry to hear about your issues with the Mira Sideboard. The Mira range has been very popular with mostly good reviews. It does seem that you have been very unfortunate and I hope John Lewis will be able to resolve this problem for you.
I note that there are currently 12 reviews for the Mira sideboard on the John Lewis site, again mostly positive, but 3 negative which are, obviously, from the same person. You may reply to this post but we will not be publishing any further reviews from you on this matter.
