I have been double charged for TMM and have been sent 2 invoices even though I only have 1 account. What should I do?

If you have been charged twice it means you have signed up to The Mobility Manual twice.

If this is an error, please send a message to support@mobilitymanual.com and we can check your account. Once we can confirm that you've been charged, we will process a refund to the other account immediately.
