Worcester do have a very good customer service, probably the best in the industry! ( Saying that helps me to get my jacket! )
They will not want to have their boilers described as not working properly.
Unfortunately, as you dont really know who came and on what basis, that makes it a little difficult do do anything official after so much time.
I suppose you could write them a letter ( yes, I said write! ) and perhaps even direct them to this thread ( so they can see about my jacket too ) and they might just possibly get their local staff enginer to pop by to identify the fault that Ian and I are convinced is there.

That's a good idea Tony! I write a very good letter! So long as I can type it and use a printer!
They may just at least acknowledge the problem. I may have the old paperwork somewhere, it would be worth trying to find it.
Thank you
Ani
