Yeah, good news mate, hope it works out when you get them back. However, if I lose a custy for a cheaper offer, I wouldn't want them back, because of the chance they'd do it again. There are too many doors to knock and too many people who want a windy, so why should I take one back?
Same with bad payers. Never had one change. In the past when I've dumped a bad payer, if I took them back, they behave for a while, then become a bad payer again.
Maybe not all the same, but I find once they'r off the books, they stay off. That's just the way I see things, it's upto others what they do.
Glad your happy with it though. All the best.
