dixie I would have thought they would have called by now. I thought they had to give time slots now? Horrid having to wait, plus you should know when they are coming so you can take pain relief and shower beforehand. Hopefully when they do eventually arrive, you can perhaps arrange a set time for future dressing changes.
mrsWee I feel your fear. I have been in tears over the tax credits on many occasions. We have been selected for a review, and I thought all the info had to be in by the end of this month, like it does for the renewal, but realised Friday evening that it was end of May! Had to wait until yesterday to call them. They were fine about it, just said send info in ASAP. You have until the end of this month to renew, so do it soon.
What will be will be. They will not send you to prison, or fine you, unless you have been intentionally fraudulent on a grand scale, like claiming for kids you do not have, or saying you are single when you are not.
My DH had not earned a penny the year before, and earned 1K this year, plus made a loss on self employment. Thankfully he has a very large c**k 
The childcare payments is what I am worried about, as we may have claimed for more than we had used, but we had two in at the same time for 3 months, then one in and out of after school care, plus we dropped and increased the other ones nursery hours. I would have been calling them each month. I think they understand that people's lives are in a constant state of flux, which is why they do it retrospectively.
I previously had the childcare voucher salary sacrifice thing too.
