So let's see...
The exact 2 punters to stand-up for her on this thread, have also both posted Positive feedback for her on AW (unless it's coincidence they should share the same online names).
Is this not a form of what many of you's call 'White Knight'??
I think even if the excuse given was genuine then an offer of compensation may have been welcomed and all of this most likely avoided.
She gave an excuse, whether you choose to accept it or not is totally upto you. Why you think you deserve compensation for it because of what's happened though I don't understand.
I've not met her though so don't know whether or not she'd offer some form of compensation as a good-will gesture. If she does, it's at her discretion though
The way I see this is something came up.
Whether that's bull or for another reason who knows.
I'd go with that.
*She or whoever was manning the phones may of forgot to pick it up when leaving flat, or they didn't leave flat at that exact time but where otherwise occupied discussing & trying to sort out whatever the private problem was so couldn't answer the phone
*Merely an assumption of a possible scenario which may of occurred, however...
Truth is, well never know the real reason why booking didn't go ahead
Anything we come up with is merely an assumption as we only have the OP's comments to go on.
