It all started in The Capitol Centre Store, Preston, where we walked out because the operative tried to hard sell insurance on a TV surround sound system by telling us we couldn't even get a refund on faulty goods without it !! So.... we visited the Chorley store to buy the same Sony system (£179.99). We were told, as with Preston, that we had to buy an optical sound cable (£50) to go with it. Researching at home we found the 'optical' cable was in fact, not as good as an HDMI one and so we returned this expensive piece of equipment. The store assistant re-iterated that the optical was definitely superior and so we bought a cheaper one for £19.99. This we opened before the main sound system....... Lo and behold!! The sound system came with an optical cable......... now we have an unwanted cable that has been opened and Currys won't refund the money. Plus - further reading confirms that the HDMI cable IS definitely better for audio. I will never trust Currys staff again. They have wasted our time and money and in future I have no intention of visiting your stores or trusting your staff. We are both over 60 and the staff seem to think this qualifies us for a good scamming. As they all seem none too bright, they probably assume we aren't either.......... how wrong they are.
