Terminix tick protction - horrible service Newburgh New York

I bought tick protection where they will come out and spray and if problems they will come out again.  The first man took a lot of time to spray but we were still plaged with ticks.  The second guy "said" he sprayed the entire 2 acres in less than 2 minutes.  Several days later, while working in the front yard, I found three ticks attached to me and a number more in the coming day.  All these were near our house. So I called Terminix.  The first lady who answered was very nice and when I asked to speak to a supervisor of our service area office she said she left a message with that area manager - no one called.   The second time I called I asked for a supervisor who was above our area office and asked for another spraying.  We stayed home on the day that they were suppose to spray but no one came and no one called to say the spraying had been canceled and no supervisor   called from any office  as I had asked.  So after not hearing anything from Terminix for several weeks I again called to find out when the next spraying was.  This lady did have a date but Terminix didn't inform me.  Very calmly and being nice I again asked to speak to a supervisor.  This time the lady asked me why and in a calm voice I went over my recent history with this company - she hung up on me.  The service in so very many ways is extremely poor and I very much question if the product works.
