Cant cancel the avast cleanup subscription

I started the free trial last month and i’ve been charged. When i go to the page of manage subscriptions so i can cancel it, it appears the option to buy it like if i don’t have it. In the app for microsoft I have it and in the web i don’t. I can’t contact with the support team because the telephone numbers are from other countries and i will be charged for calling. Can somenone help pls.

You and me both. Clicked unsubscribe on two separate occasions and still got billed. To actually unsubscribe you have to navigate through several not very obvious or easy menus. Hopefully they will refund my money. I won’t let this go as it is hard enough to simply afford the programs without getting billed for something I no longer use and is difficult to unsubscribe from. They did not respond to my reasons for unsubscribing, despite submitting them twice.
