That's unacceptable.  Is there anyway they can see sooner as it is their fault not yours. I don't think some doctors understand how anxious  you get waiting .

Hi,

have you managed to speak to someone to get a new appointment date? It's crazy that things are all posted when email would be a lot quicker! And cheaper! And more reliable! I had a letter arrive telling me my pre-op was the day before - luckily I had had a phone call to say ignore the letter as cancelled but had that not been the case I would have been devastated to have missed it and then not been able to have my surgery. 
fingers crossed you get news soon - I find that the waiting is so hard. x
