S.Anderson in Sherwood park

My septic service was not working efficiently. This company gave quick service but took several attempts to trouble shoot the problem, even then they were not completely sure and so replaced the septic pump. I made further enquiries and found out that I had been charged !00% markup on the pump ( approx $500.00) Also, this company advertises that it has been in business since 1986, but has been sold in recent years and is operating under different ownership. Why are they not a member of the BBB? .... where reviews from all customers can be posted. This is a 1-5 million dollar annual revenue company.
