Cheers for the reply lads, and I can see the error of our ways, but to clean a few things up...

1) The seed has been caught out by snail mail, which went out on the 1st April, a total of 4,400 records was mailed.

2) The record stems from a list that was brought by the company back in 2003, in this year some idiot added it to the company DB without checking that the information was correct.

So we now have a DB of 18,500 records and a seed is in amongst this lot.

I beleive chip is right, they have us by the balls and the best thing to do is pay the subscription again.
