Thank you Bob. In response to my email:
"Dear Jovana, as I have heard nothing more from Avast I have uninstalled Premium Security and terminated my subscription. Please can you confirm that my Subscription is terminated and that no attempt to charge me will occur on 12th April. Thanks".
I received the following a short time ago:
"Dear Mark,
Thank you for your reply.
I sincerely apologize for the mistake, as I assumed that you have a Windows PC.
Please note that I have came to such conclusion since you have a subscription that is only compatible with Windows, and that is also the reason why you are not able to activate it on your Mac.
If you are still interested in using our product, you can check the below link, where you'll find a trial subscription which is compatible with Mac.
Additionally, the renewal price will be 40% off the full price for the first year.
40% off Avast Premium Security for Mac (60-day Trial)
I am truly sorry that I wasn't able to provide you a better support earlier, however I hope that the offer will meet your needs and that it will compensate the fact that I didn't check all the info.
Looking forward to hearing form you.
Hope you have a great day!
Kind regards,
Jovana,Avast Customer Care"
I find this response truly astonishing and replied as follows
"Dear Jovana,
my subscription ID was 13915557110 and was clearly for 1Mac so I do not know how you have come to the conclusion that I have a subscription that is for a PC. It proves to me that Avast do not know what they are doing.
Please will you confirm that my subscription is cancelled and that there will be no charge on 12th April as I requested in my previous email."
Anyone got any further comments?
