Top up account

Hi Does anyone know how to cancel a top up? I was trying to add a small amount to ensure it was clear but I can now see there is a fixed amount suggested on the top up page and before I knew what had happened there was a message displayed saying thank you for the £50 top up! I only wanted to add £5! Anyone know how to cancel this please?Thank you

The best suggestion I can think of is to contact the Bulb help desk, their contact details are on the bottom of the Help page.
