Disappointing. We traveled to London and my mother was looking forward to experiencing this store for the first time. She unfortunately started to not feel well. I went to customer service to see if there were wheel chairs available, only to discover that this great store doesn't keep track of them. There was a sweet woman at customer service that tried to help. Sadly, while she was trying to place the call for help, she kept getting the run around. How hard is it to make customers sign wheel chairs in and out? Or to put something in place to make sure that wheel chairs are all returned to the same area?
