A b/w to me is a cheap woven carpet that can not be cleaned with h/w/e you just think water and they will shrink
back in the day you used to see loads of them, few quid a yard , not many now ,if you did clean one they would shrink bend buckle ,you could not kick them back out no way
I clean lots of woven carpets no problem ,but not them no way
why would you let a Customer tell you a carpet is not going to shrink ?
why has she not used the same cc as last time ?
it sounds like your getting set up for a claim
