Claims to be BT head office but knows nothing about the local infrastructure. Tries to use copper lines being cut off as pressure to divulge contract details.

Nasty man saying he was from BT. Got very aggressive when we questioned his claim to be from BT. We asked him to email us with relevant identification and details of our account to prove he was genuine. He then threatened to cut us off, and then hung up!
