Andy Bennett billed 4 co-owners for reparations to a shared drive. His work took ages to complete, though it was to a good standard.
I am amazed that he included GST twice, to at least 2 owners, thus making an extra $50.00.
I brought Andy's attention to this error in my bill, for which I paid the correct figure. Fortunately, I contacted one of the co-owners, only to learn that this oversight had not been checked in his bill either.
He is not exactly in-expensive, so I will be contacting my Property Manager, to use another plumber, in the future.
