"John" called. Heavy foreign accent. Tried to say AT&T was upgrading my Direct TV receivers so I'd never again lose the satellite signal, etc. Upgrade would be free and also a $20 reduction in my monthly cost. Gave me a callback #203-350-9750, x-8019. Asked for updated credit card info, which I did not give. Checked with AT&T and this call was not from them. Beware of this scam!
