Postcode location. Recent non delivery and cancellation of supermarket food delivery (we are self isolating being classified as extremely vulnerable), as the driver couldn't find property as postcode didn't exist, and that's all he had to go on - no address, apparently, no map, no local knowledge! We are in a new property, so unless the company has an up to date postcode register we simply don't exist. We now know a longstanding local postcode which we give drivers if they call, along with local directions such as 'turn left after the village green', but not a sensible state of affairs in today's tech environment. This is just the most recent incident, and we are hungry! Why don't they USE MAPS! - or an A-Z, even?
