Is there a telephone SCAM concerning upgrading Directv receivers?

Beware of an Att/Directv scam. Someone calls claiming to be Att/Directv, they tell you they are from Directv & you need to get an upgrade on your receivers. They ask how many TV’s you have. Then they transfer you 2 times. They explain Directv is upgrading there services and they do the upgrade and due to the Pandemic they can not come to your home. So they are able to upgrade through the Directv technical center in our area. They say you must get this upgrade to keep your service over the next several months. The system must be upgraded or eventually you would lose service. So to get the upgrade you need to pay them $150, now, and then you will receive $40 a month off of you bill for 2yrs. They will do the upgrade, increasing the number of channels, the number of programs you can record, and improved picture and better sound quality.  He told me told me my name, address, and the kind of the receivers we have. He was wrong about the receivers. He “checked” on it and told me I was correct and they all needed to be upgraded. I started asking questions. Like, why don’t they just take $40/month until $150 upgrade is paid. He said they do not own the channels and billing and technical could not be combined.  I asked why this wasn’t sent in a letter or promoted on a message on Directv. He said it would be on Directv and I should have received a letter telling us to expect this call and explaining the situation. 

I googled Is Directv upgrading their equipment, while he was talking. I found a couple of similar incidents. I asked him for a phone number and told him I would call him back after I called and asked Directv if this was a scam. He assured me it wasn’t a scam and he gave me a phone number. I googled the phone number he gave me. It is in NJ. I called Directv
