I don't think that there is a Data Protection issue with the mailing list. All Creditors of SFT are entitled to a list of other creditors. So for example if SFT purchasd a computer from PC world on credit PC world could write to you asking if you want to buy their wares!
But, yes some people could be offended by the mail shot, it rattled me a bit, but how do I know that the Bank application that came last month wasn't from the same source?
Chill.
