My daughter had a epilepsy seizure and we asked to move our appointment for just an hour or two, as we were behind schedule. There response was just, no you can't amend time slot and a condescending, if there is anything else we can help you with rubbish. It was just visiting the tall building with a view, nothing that couldn't be easy to sort. Its a shame as there is 55 of us and we were a day early, so im not recommending to book through this company and after reading some reviews after this has happened, I shouldn't of booked on with these in the first place
