Input: I called to get a toilet unclogged.     After 2 attempted the tech stated I would need a new toilet and he recommended the $1000 fix.   He said in 2-3 days it would be clogged again.    He charged us $227 and asked if he would get 5 stars for his service.    What????   I called to complain about not having value meet the mark of the amount paid.   Customer service called and said they would call back in 24 hrs.   No one has ever called me back.   Awful company!
