What can I say, other than ask if anyone else have been shafted by these cowboys and paste my response:
Hello,
I have just received this email stating that MY ORDER MAY BE CANCELLED BECAUSE YOU CANNOT USE MY CREDIT CARD ACCOUNT.
There is absolutely nothing wrong with my credit card. I know for a fact that there is a definite problem with your inadequate system.
I have checked on your website and I find that the order has been cancelled.
HOW DARE YOU!
I have waited 5 months for my Vista upgrade (order number XXXXXX. I have phoned you several times to check on progress and you have provided full assurances that the upgrade will be OK.
I had a similar instance with a previous Vista upgrade which was eventually cleared up by you.
I have been shabbily treated over this order and I most definitely will not leave things as they stand.
I require a speedy reply to this mail and in any case I will be phoning your office at the very next opportunity.
Yours,
Blah
