"Orthotic shoes at Prince Royal University Hospital"

I was sent by my surgeon to have a pair of blue trainers made with a heel raise and orthotics made for the shoes. I am a size 6. When the shoes finally arrived ( about 6-8 weeks later)they were a size 5, so they had to be returned to have another pair made with a heel raise. I finally received them another 6 weeks later. When I went to collect another shoe later in the year which I had had raised it was suggested I order another pair of trainers with the heel raise. It was agreed to do this pair in  a grey. I waited 6-8 weeks and was contacted to pick the new shoes up. When I went to collect them I checked the size which this time was correct but they were blue not grey!

How can they get these things so wrong. I have now got to wait another 6-8 weeks for a new pair of shoes to be done
