They keep calling saying they are from British Gas, (indian lady called Catherine and we have had rebecca called 5 times with a very strong indian accent as well) wanting to send one of their engineers to check our meter, total scam as we have spoken directly to British gas who have no issue with our meter/billing, apparently they try to get the details and then sell our details on to another energy supplier and reap the benefits British gas have stated, do not fall victim.
