Phone call from South Africa telling me energy provider wanted me to upgrade my meter. Thinking it meant meant my electric and gas meter. He was extremely insistent trying to get me to authorise a date. After watching many consumer programmes I told him I was going to find more information. He was getting extremely annoyed and unpleasant. I discovered after looking into it it was an underhand tactic to get a smart meter fitted. They have a schedule to fit these things so that was why he was so
