My mother was called at home. They told her about the septic tank cleaner to try, if it didn't wok she could return it. She gave me the bill to pay I wanted to know what it was for, so I called . When the lady answered the phone she did not say anything until I said hello. I asked what it was for she answered pour down the commode to flush it out. I told I need to return it she said it was to late ,it only had been about two weeks. I told her she took advantage of a 80 year old lady. She told me if did't pay it would be turn over to a collection agency, I haven't paid yet the order was in July 2015. No collection letter yet.
