Sorry another party invites moan!
Sent out the invites with 4 weeks RSVP date on them.
Majority of people replied within a week of receiving them - fantastic.
3 people hadn't heard from 3 weeks before RSVP, and as required booking, wanted to check that they had a) received invite, and b) were aware I had to have the decision by the RSVP date, no flexibility for later.
2 of the people apologised for not getting back I said no need as they weren't late and they said they would be coming.
3rd person said they hadn't got back to me, as they weren't sure whether they were coming or not, so I should assume no, but if it was yes they would let me know before RSVP date.
RSVP date arrived, I'd heard no more, so went with the numbers I had - now almost a week later I've received a text saying we've changed our mind, we now want to come.
I've replied sorry too late all booked and paid for.
Now thinking am I being harsh, it will cost me more to add them, but I may be able to add them at a cost, should I respond (once I've checked of course) I've found I can add more, but the additional cost over the top of the original price is £x (likely to be almost double the original) you will have to pay the difference?
AIBU?
