Our washing machine started leaking with no obvious source. NAC sent an engineer the next day who located a faulty hose. A replacement was installed the next week but then another leak was discovered. The faulty parts were again installed the week after and now we have a working machine.
What could have been a frustrating process with a couple of repeat visits was made completely manageable by the honest and open communication of the engineer. The lack of additional labour costs were a nice surprise too!
I was very impressed with the whole service, would recommend, and would use again myself.
