Years ago, when I still bought from Q, I thought their invoices were carp. I was never unlucky enough to be wrongly charged or overcharged, but one of the reasons I stopped shopping with them was when I bought a piece of jewellery and the presenter had said, during the presentation, that the invoice sent with the item would contain "full details of the item purchased, type of gold used, gemstones used", etc. etc. When the parcel arrived, did it heck contain "full details" - what a load of horse hockey that was - the invoice contained about 5 words, none of which described the carat weight or type of gold, gemstones, etc. and there was at least one misspelt word in the description! When I rang "Customer Services" (so-called) to complain, the operator firmly denied that the presenter had said it - until I told her I had a recording of the hour and would take this further. She then asked me to hold on, and when she came back simply apologised, saying it was a "misunderstanding". Yeah, my right leg it was. I took a photocopy of the invoice and sent the whole lot back, with a short and to the point note telling them I'd better get my refund plus both lots of p & p pronto. To be fair, they did refund me within the week, but that was the end of my buying from Q - you only do that to me once and that's yer lot!
