Re: Why?
For me it is the reliable phone line or effectively no communications. We live in a house which has very unreliable mobile service.
I am not now with BT as such any more and never had their broadband. Yesterday my wife fielded one call about 'our 'BT BB yesterday and I had one today. The idiot was so shocked to hear that my (non) BT was in fine health, I almost felt sorry for them.
Once around Christmas I was doing something with BT and also had a bank statement on my desk. A scammer claimed that a payment had been missed, when I had several proofs to rebut his claim I just wish the scum could get an 'honest' fraud.
