Mike,mmmmmm,this is a tough one,or could be.At least the
Value of the rug is only £300 and it is 2 years old.
This is the `snag`from your point.
What has happened is of a direct result of your actions….ie.
The cleaning process and your cleaning method.
Your `saving grace`could be the urine,which we all as cleaners
Know is `potent`.
It could be the urine,it`s difficult without seeing it,can you get any
`pics`down for us to look at ?
Depending upon your individual customers attitude towards the rug
And yourself,you`ll soon be `throwing good time and money`after bad.
Your really in a better position than I was with that suite ( too long a
`diatribe`to go into in an e,mail )
Don`t `bank`on Next being liable for an item deemed to be unclean able
For the reason stated above.
At this point in time let someone else do the chasing around and see what
Happens and take it from there.
