UK customer phone number doesn't work and no answer to my email

Hi, I’ve been trying to call Avast customer service multiple times and every time the phone number doesn’t work. I also sent an email a week ago and has gotten no response. How do I get to get in touch with them? Thank you for your help

First, I’m an Avast user and not an Avast Team member.

I don’t know where you got the number from, but I don’t think there is a direct line, contact outside of using the avast support web link.

What is it that you are trying to contact about ?

You could try here

But not knowing your problem it is hard to say if these are related.
