Your delivery process leaves a lot to be desired. I have just obtained your product so haven't had the opportunity to fit and try it yet. However I found having to sign for the delivery to be extremely awkward. I am never at home during the day and have no neighbours. I had to drive a 50 mile return journey to collect my parcel and finding the actual depot was also problematic as it wasn't signposted (it is located behind an old factory estate which is a wasteland) and due to automated answering system I could not contact them to find the place. It took 45 minutes to find them. This is the only time I have experienced this level of inconvenience for obtaining a purchase bought on-line.
