Morphy Richards 73168

I have been trying to find dust bags for this Morphy Richards vacuum cleaner and it is impossible! I will never ever buy Morphy Richards again as it's just such a mission. I've been to at least 8 shops and called 6 more and no one stock the bags! When I called Morphy Richards they say I can buy it from them, it will take 7 days to deliver and they don't have a list of their stockists. When I told the lady that I now have no choice but to buy a new vacuum cleaner, she laughed at me!! But what am I to do? My guests arrive in 2 days and my vacuum cleaner is so full it won't work. Never again!
