We hired DeTemple to do some simple plumbing work. They sent out a sick employee who worked very slowly only getting about half way through the job. He ended going home sick mid-day and not returning to finish the work. The next day, a new employee came out and completed the work in 2 1/2 hours. When we received the bill - it was much more than we expected, especially for the hours of work completed by the sick employee, who was not functioning. We called and spoke to De Temple and the employee agreed that there should be an adjustment due to the sick employee's slow work rate. That day, we mailed in a check for the agreed upon amount in full.
Days later, we got a call asking why we shorted our payment and we explained our situation. Again, the employee agreed that there should be some adjustment and he gave us a new adjusted price - not as much as the original employee gave us, but it was something.
Returning from vacation, we received a note saying we are being sent to collections for the original bill with no adjustments. Now, the company says the employees that offered the adjusted amounts were not authorized to adjust our bill and we owe the full amount.
