Just another one of the many nuisance robo-calls of late beginning with the false claim that you are a past customer. This one goes on and on offering various services (including carpet cleaning). At the end of the spiel, you are given the opportunity to get off their list by hitting '9', which I did ... but past experience tells me my request will be ignored.
Robo call stating that I am receiving the call because I am a past customer. I am not. This is a carpet cleaning company. I just moved from a house with all wood floors. We had no carpeting at all. I followed the direction to speak with an operator so to be removed from their call list as I've found leaving instructions at that option on the call menu does nothing otherwise. No operator was available and voice was full. I called the number back and was able to leave a message, which I did, informing them that I am on the "do not call" list, I have never been a client of theirs and they are to immediately remove me from their list. I also let them know that I would be filing a complaint with the FCC.
Have been receiving many robo calls recently on my landline & cell phone at very bad times. There needs to be legislation to stop these calls. I am not a past customer either; that's a lie they start off with. This one left no message, but interrupted my sleep.
They've got to have some reason to call you and try getting information, regardless of whether you're a past customer, or not. Without a pitch like that, they'd have nothing to try and work with.
