I couldn't understand the name of the person they asked to talk to but I could hear a lot of background noise so I could tell it was a call center. I told them they were speaking with Senior Taco and asked how many tacos they would like to order. The caller got confused and hung up.
A man called me claiming he was from Solar USA. I explained that I am on the National Do Not Call List and he is not allowed to contact me or I would report him. He then started to get very vulgar and stated I am going to f**k you, I'm going to f**k you. I had to block the number.
Called several times over the past few days. Finally my wife answered and a man with a strong (Indian?) accent claimed our electric bill was more than $100. We told him it wasn't and he hung up. I think he wanted to sell solar panels or something. Seemed like a scam.
