I’ve just had a reply from Avast Business even though I am not, never have been, and (being retired) probably never will be a business customer.

They again gave me a telephone number but AGAIN stated that telephone help is not available to UK customers.

He suggested opening yet ANOTHER ticket - that would make 11 over a period to the address that refuses to reply. Most of those I have deleted to save space so it seems that Twitter is really my best/only hope.

I shall commence tomorrow, but in the meantime thanks for your help.

Looking on the forum, it seems that almost every post is about Avast’s failings. They are possibly getting too many complaints from US customers, hence no time to bother with those in the UK. They only have time to send out automatic bills to us!!!
