2 wks before christmas I cleaned a 3+2 sofa, 45% viscose, and polyester. I thought I had brushed the pile the same way, but I received a call from the customer concerned. I called round and yes some parts of pile on the fabric had dried the wrong way. I explained what had happened and said that it could be easily rectified by slightly dampening the pile and brushing the correct way. They where still concerned and would not let me correct the sofa, but agreed for me to take a couple of cushions away with me to bring back, which I did and in my opinion was back to normal. The next day the customer rang back to say they are not still happy, and looks like they are after a new one.
Advice please on what do you do next, when the customer thinks item is damaged and you know that there is nothing wrong with it, and they will not let you put the job right. The upholstery is 2yrs old, and they are comparing the cushions I have done to the swatch sample on the base.
