Unable to cancel Avast Cleanup Premium free trial on the last day

It’s me again,
today i received an email of successful “subscription renewal” for 1 year at cost of 49.99€.

Yesterday(before the expire date) i sent you the above mail and i tried to contact avast support in different ways like site phone and the phone number indicated in the mail link avast.com/find-order but the number doesn’t exist.

I ask a refound for the amount since i asked the cancellation before the expire date.
Old order ID:28270722408
New order ID:57814159600

Thank You and have a good day!
