This number has also called my landline but is blocked immediately after the first ring. I normally do not call numbers back but since it is blocked decided to see what would I reach. It was a generic recording that said thank you for calling back, we are assisting other customers, either we are closed or not at our desks. No company name was given and in order to be removed from their list, they wanted your full name, full address and telephone number. Needless to say, I did not leave any information however, when they said they welcome feedback, I was very polite and inform them that I knew they were a scam. Had it not been blocked, I still would not have answered it since I do not answer any unrecognizable numbers.
