LOL, there is some funny information in this thread including an address/phone number last used half a decade ago or more, and some other poor bloke's mobile, name and address. (And also 4Edge's number just in case anyone wants to harrass the neighbours. Nice!)
The company stopped supplying PCs
to the general public two years ago and retained those Hockley premises as the lease is not yet up. But, did you try the obvious route of emailing them? Try webmaster ==at==bestpricecomputers.ltd.uk and if you use
saynoto0870.com as your subject you can tell the company why you won't be calling their 0870 number and your email
will be read
(As webmaster I'll whitelist that subject title for the next 7 days)
Don't be surprised if you don't get an answer though.
