I am fascinated by the map tracking thing Amazon do. I have learnt not to trust it 100% though. At least once, I’ve had great fun watching the van get closer and closer, sometimes stick in the same position for 30 minutes, then apparently located yards away from me ... but 2 minutes later, it’s gone past and round the one-way system. I complained once because I was waiting for a present for someone I was seeing next day - it had already been delayed as it had been due the day before. Anyway, according to the map tracking, it had been past or within a few houses no fewer than four times. I was so frustrated! When I rang or live messaged, they arranged for it to be delivered early next day and gave me £10 credit. Their CS, as you say, is second to none.
