Joining bulb

I signed up to bulb a couple of days ago. Although it was easy… It was a little too easy as I hadn’t intending to switch, only to compare. So I had second thoughts and cancelled the switch.
Now I’ve had time to compare my current tariff against all others I would like to proceed with bulb.
Can my switch be reactivated please?

I think NOT. BUT you can re-apply again without punishment. Use someone’s referral link and get £50
