Hi,
I have, but I still can't understand what was wrong with the post?
Show us the things you are talking about!But I note you have posted the PCN, I missed this originally, sorry.
It looks like a typical “double dip” so you need to tell them accordingly, ie their equipment is faulty and their claim is wrong and you won’t be paying.
Bottom line is that if they insist on pursuing you we will advise at each stage, if they don’t see sense.
Apologies, there are too many people here who
don’t post relevant information in the way that you did.
