Please, please help me

I need to contact Avast support for both a refund and because I was charged 25 times the normal amount for a monthly service. I cannot enter an order number in the field to submit a ticket because the order was done through Google play.

I need a refund and cannot find a way to submit a ticket because the order number field to submit a ticket is a required field. Can someone please, please help me?

I was charged the $2.49 for a monthly fee then a few days later I was charged more that $54.29 a few days later as another recurring payment. Please, please help me!
