subscription payments

Avast appear to have taken the wrong payment from my bank account. I was advised that I would be charged £29.99 for one years subscription in their email of 31/12/2016, which referred to an original Order Number but I was today advised that they had taken £39.99 from my bank account ( quoting a new Order No.). Does anyone know how I contact the relevant Department within Avast to request a refund of this £10 over payment?

Hi adam289!

Sorry about that, I don’t know what happened there :frowning:
I am at the moment issuing your refund of £10. We will investigate what happened and fix it as well.

Thank you for confirming that you will arrange the refund.
