Octopus Energy - any connection with Bulb?

Just received a “statement” purporting to be from Octopus Energy. I’ve heard of this company but am not a customer, unless anyone knows of any connection with Bulb??

Nothing has been reported by Bulb that they have a tie up with Octopus Energy…

You should easily see if the statement is genuine by looking at all the details on it and comparing these with the most recent statement from Bulb. Can it be assumed you are a customer of Bulb?
