A man called Richard claiming to be from Yellow Brick Road, I have contacted Yellow Brick Road and they have had many numerous complaints. The man had an Indian Accent and when I questioned him further and told him I would be making a complaint he threatened me 3 times, stating that I will be sorry for reporting him. He then hung up. The number is no longer in operation.
Yellow Brick Road have been very helpful, so it's a shame that their reputation might be tarnished from these scammers.
