Tried helping somebody submit a reading to Octopus and their website is conveniently broken and I'm really struggling to get a reading submitted.

At 10pm we’ll be offline a maintenance window to bring additional capacity online - it should be no more than 10 minutes.
We're super busy today so you might have a long wait if you call.
The best day to give us a meter reading is this Saturday (our standard variable prices don't change until 00:00 Saturday 2nd April.) Make a note of your readings or take a photo of them on Saturday. When we receive this reading we will apply it to your account from 00:00 midnight on the Saturday. You will have a week to submit them to us, so please don't worry if you can't get it to us that day.
Smart meter customers do not need to send us a reading.
If you're on a Fixed tariff, it's always good to submit regular readings, but your prices won't be changing so we don't necessarily need one right now.
