I have receive my email to tell me I should receive the introductory cash from RansferWusr after my first tip up and they have not sent an email for my details to pay… Have I been falsely duped into joining bulb on a false promise of a cash payment on joining?

Not a false promise please see:

If this time period has passed I would contact the Bulb team direct, you can find their contact details by clicking the Help button at top of this page.
