Paul was offering to go back and put right, but the attitude of the tenant stank! The Letting Agency, should have taken control of the situation, by letting the tenant calm down and then taking Paul back in. 
Thanks Helen.
I did offer to go back and correct what the letting agent (customer) told me was the problem.
Upon ringing the tenant to clarify what I was coming to do, that is when she blew up and started yelling. Accusing me of not cleaning it properly, dirt marks everywhere, that I just pushed the dirt into the carpet :

, and that it must have been a rush job for me. Took just over 3 hours for 3 rooms and a hallway - hardly rushed!
As mentioned I could hardly get a word out so didn't even get the chance to offer to do another full clean before I believe she pushed it too far, i.e. claiming she is going to make sure everyone knows what an awful company mine is and put it about on the Internet.

As stated previously the letting agent was happy with the clean, they are the ones that booked me and paid me.
As a good will gesture I offered to return half the tenants end of the payment so the letting agent had something to play with as a sweetner for the tenant.
spending time posting on the forums,
I understand everyone would deal with it differently but isn't the forum for advice.
