I accidentally booked exactly one month ahead and found the stash point closed. I contacted the web chat and they identified that I had made my booking for the following month. They gave me a code to rebook and told me to find the closest stash points that were open by using the map on their website. I just managed to rebook and take my bags to the alternative stash point just in time for my London Underground tour (where you are not allowed to take large bags). Many thanks - at one point I thought that I would not be going on the tour!
