Gosh they really are rubbish aren't they? And you are still being very nice, saying you don't want the price honoured - if I'd had it agreed verbally and in writing I bloody would!
I definitely think speaking to someone further up the chain has to your next step.
I know, i flit between wanting to push them to honour the price, and just wanting confidence the rest of the event will be alright. It would be nice if we could find something in the middle - we pay for a few changes but not the full amount they're asking for.
I've emailed their head office very vaguely to just ask for a contact of someone i can talk with fully, and if i haven't heard back from her by Sunday ill send it over to them.
Her lack of response to anything makes it so hard, i don't think we will be able to get a meeting in next week at this rate.
