Hello @amyloo ,
That is a great question! It'd be best to contact our Billing team in regards to pricing changes. They are the ones who would be able to provide this information for you. We also make our customers aware of any changes to our billing or prices through the contact email listed on the account.
OK. I was hoping to avoid telephone contact, but I suppose I can make myself call. Funny how you can now avoid it for most situations in life if that's your preference.
