Horrible...without even hiring him! We recently had a mound installed and approximately 3 weeks prior contacted him to request a tank pump out as it was needed prior to final mound installation per county's request; a price was set and Bill indicated we were on the list. After contacting him today (3 weeks later), he stated since we were a last minute request (which we were obviously not), that we would have to wait several more days as well as stating the expense for pumping went from $175 to $225! Unfortunately, he was unwilling to assist in getting our tank pumped and had a poor attitude towards the ordeal. Long story short, I wouldn't recommend trust Bill (Dundee Septic) any further than I can throw him...
