Called my cell phone twice and hung up. They do not identify themselves or leave a message. I called the number back on my landline. Number only goes to a recording. Some sort of telemarketer that says the DO NOT CALL LIST does not apply to them. Recording says will keep trying my number. Sounds rather threatening and not at all professional. Said to stop it have to call another number. The number was given very fast and was not about to call again to write it down. There is no way to stop the caller from the number that they use. I made a complaint to the do not call list, not much good with that.
