Hello guys - and thank you both for your replies.
First of all - am really sorry for confusing you Terry. I first read your message on my phone during a brief break in a movie we were watching tonight and I really just couldn't work out why on earth you were confused. Then just now I read my original message and realised that I had made a really stupid mistake!
At the beginning of my message, I said 'my old Dell laptop' instead of 'my old Dell desktop'. Such a silly mistake - and the silliest thing is the fact that I read the message over a couple of times and didn't spot the mistake! My only defence is the fact that I posted the message in a bit of a hurry this morning, before going out. The mistake may have been further compounded by the fact that I mentioned the fact that pcupdate.co.uk is associated with laptopparts.co.uk (because some of the emails they sent were from the latter company). The drive I was buying from pcupdate was however definitely a desktop drive and not a laptop drive.
Just to clarify then, my old XP desktop is a Dell Dimension, while my laptop is a Sony Vaio. Once again, apologies for confusing you. (If it is any consolation, I am even better at confusing myself than I am other people!

)
Phill, hope I didn't confuse you too. I don't think we are going to be charged for the dodgy purchases, though we will have to see when we get our next statement. I think the lady on the phone said something about at least one of the payments being declined anyway. I wasn't very inclined to ask her a lot of questions as she really snapped at me once when she asked about one of the payments and I mentioned another one of a similar amount around the same time which was genuine. She told me very crossly to only answer the questions she asked - so after that I just said as little as possible. It was not necessary for her to snap at me like that!

Writing my message here today made me think about what else I had purchased recently - and funnily enough (in light of the stupid error I made in my message) my thoughts turned to the laptop drive I purchased. This was from a company called drives-storage.co.uk which was the only place where I could find a drive which was specifically mentioned as being for a Sony Vaio. I looked them up in Google this afternoon and a site called scamadviser.com came up in the search results. If this site is to be believed, drives-storage.co.uk is very risky because of possible links with China. Very interesting!
I only normally buy online from sites I know well like Amazon and am not really very savvy about the possible dangers. Will certainly be more careful in the future though!
Once again, apologies for the error. I hope you both have a good week, whether at work or elsewhere.
Chris.
