I had a TV which wasn't working, was still under warranty and couldn't find my receipt.

I telephoned Directtvs where I had bought the product and spoke to a super chap. Not only did he help directly with my query (which was to find an invoice) he went on to explain how I should handle my calls to Sony and what I should expect from them as a customer. He was well informed, practical, efficient and kind. Customer service in the UK is generally very poor, so my delight in finding such a helpful man has led me to post this review.
