Best Sewage Ejection Pump Repair in Chicago IL

I had a gangway sewer plugged up and backing up Water. They rodded the main pipe from roots of a tree in the pipes. It cost $425.00 the person stated he rooted out the pipes to the street. It did not fix the problem. They stated they do not guarantee to fix the problem. They said to try to fix the problem would be another $1200.00. Again no guarantees. They try to fix the problem by trial and error. Not very happy with this company.
