I keep getting calls from a Melbourne number, which I have been ignoring.When I did answer, I got a guy with a heavy accent (hard to understand), telling me that he was from AGL and that they were offering better rates than I was currently paying. He did know my account number, but the rate information he was quoting did not seem correct.I asked him, "If AGL wants to lower the rate, why not just do that? Why do we need to go through this?" No real answer to that.Does anyone know if this is legit ...
