Do not use PHS! And if you have a contract, read the small print very carefully. They operated a rolling 3 year contract with no break clause - and still insist on a 90 day notice period. You can get sanitary waste removed at one third of their annual costs. I am appalled by their lack of customer service and have no complaints process. I cannot believe a company can operate in this way in the 21st century. Shame on PHS.
