I finally got mad at all these robocalls so I agreed to AC maintenance. A technician showed up so I told him that I just wanted to waste their time like they did me. Owner called me and agreed to take me off their call list. I'm now getting only half as many robocalls than before.
These [***] called me and I explained to them that they have the wrong number and to stop calling and this dude said "No we will not stop calling, TRICK. This dude really called me a trick so I am going to wait for another call and then I will be blocking them. I am truly livid!!
They called and then hung up. Redialing all you get is a busysignal. There ought to be a law against this that says the actual telephone used to call you must be a real number so you can block them and report them especially when you are on the du not call list.
