I think that's an excellent response! You acknowledged that she's upset, but let her know that you're not falling for the story, all in a very professional manner. Odds are she won't even reply.

I think you handled it perfectly. I'm curious to see if she'll respond.

my only suggestion is that its taken her 9 days to let you know her complaint because she was on her honeymoon

otherwise if think your response is to the point and clear that you have investigated her complaint with other independent sources and found no merit in her complaint

goodluck!

Very good response... can you write mine if I'm ever in this situation? LOL
Maybe we need to put yet another chapter to the contract. All complaints about cakes must be made within x amount of time, and a portion of the cake saved for evidence LOL

Thank you for the update. I've been watching this thread and waiting on your post . I think your response to her was perfect.
