Parking on Wallingford Way, SL6

The numbering system in that parking area is not chronological, so I relied on the photograph to find the space and I was assuming the space number would be visible. It was difficult finding the space! Then, the owner still had his car in the space at 7:40 am after I had booked it from 7:20 am. Then I rang the owners number and the line went dead after a couple rings. I tried to contact the customer service desk but they aren't open until 8 am. I tried to ring the owner again, 8 minutes later, and the owner was apologetic and moved his car. However, this all made me miss my trains and end up being late for work, which would be unnecessary if the contract worked as it should.

Quite difficult to find the space in a hurry
