I don't live in the UK, so when I saw this number, I didn't answer it. After two or three rings, it stopped. I assume that it might have been a robo called. The number is now blocked on my phone.

020 8103 3139 This number is being used by Octopus Energy to supply a code number to make additional payments to your Octopus Energy account the system is called "Link" it also uses other 0208 numbers such as 020 8103 3112. Octopus don't give any information on their payment link that you will instantly receive a call and to the warry this looks like a scam, it certainly did to me, I've complained to Octopus Energy that they should make a better explanation how this payment feature works on their web site.
