If I could give a 0 Stars I would! On hold for 1 1/2 hours to get help. It's all about the $$$. Horrible service !! I told them I'm on oxygen and have asthma. Of course they said no problem. Once installed I couldn't blow hard enough spent an hour trying and eventually said it will have to be removed. I never even left the parking lot and they charged me another $90 to take it out. $66.00 to end my plan. Ridiculous. Cried all the way home (60 miles round trip) & 7 hours wasted . Servicemen were very nice but Intolock Company is the worst. Stay far away. Don't say I didn't warn you.
