My switch to Tomato Lifestyle from Octopus Go did not go ahead on the 20th as planned. I emailed them and received the following reply. Facebook is indicating lots of prospective users similarly affected.
"Good Morning,
Thank you for reaching out to us and we truly do apologise for the inconvenience and delay in getting back to you.
We regret to inform you that we have been unable to complete your transfer at this time. This is due to ongoing issues with our switching servers and MPAS system.
Due to this, we have been unable to register this.
Once the switching servers are running, we will attempt to switch this supply over to us. We are currently in the process of getting this issue fixed, this has been logged and once this has been resolved we will then register this site accordingly. Our teams are actively working on combatting this.
We sincerely apologise for any inconvenience this has caused and greatly appreciate your patience and cooperation."
