I had similar problem 21 weeks waiting on Sofas. As we are new house owners we were very put out, with no where to sit (comfortably!!).
Like the above customer, we had to ring, continuously, to find out about delays. No calls returned! A cat and mouse scenaria!
We eventually were told that we would have another long wait after the 10 weeks were up. They did not offer anything for the inconvenience. So I suggested they give us a sofa, until our one turned up. They agreed!
I would have preferred if they offered, but hey....
We eventually got the sofa, 21 weeks later - not the agreed 8-10 wks!
