No charge for the time & effort spent on my Volvo V40!

The infotainment screen in my wife's Volvo V40 suddenly went blank, and, based on references seen, I took it to Pro Nordic Motors in Malboro for them to determine the cause thereof. After spending some time checking connections, etc. they regretfully advised us that it was a Volvo software problem, not something they could fix as yet. Amazingly, they refused to charge me for the time & effort spent on the car! This act of kindness has gained them a customer for life.
