Person on the phone rang our landline twice and our mobile twice. We said we are not interested. He said he was from some energy company. He told us not to hang up. Then he left a message on my husband's mobile saying "You have wax in your ears mate. You should listen to what people say." I am going to complain to consumer affairs.
Other numbers were 9561 8028, 9561 7095, 9561 2748
