Our TV service is through DirectTv. Posed as person from them and advised they needed to switch out our receivers. Made sure our TV was on and had me search for code to see if they were still compatible with dish. Code I gave was not. Set up appointment to have tech come to home a few days from now to change receivers and pay installation fee of $199.99. I was instructed several times to not discuss any of the details of the transaction with the tech because they were just a local guy and wouldn’t know anything about details. This made me uneasy so I called Direc TV. They made no such phone call and do not have work order on file. The person spoke with heavy foreign accent.
