The function "Cancel Subscription renewal" does not appear

Hello:

Yesterday I received the following information that I'm going to comment on:

You are writing here in a publicly accessible forum, personal data can and may not be questioned or answered in this forum according to the Data protection GDPR. Questions about your license or payment processing can unfortunately only be handled by the support team via your customer account via email in accordance with GDPR. Thank you for your understanding.

We do not have access to your customer account and cannot refund you, we are not authorized to do so. Cancellation and refund can only be initiated by the license holder.
Please have a look at the information, maybe you will find your solution there:

My comment:

You suggest that I should talk to the support team through my costumer account, but the problem is that I don't have access to this account, and consequently it becomes impossible to cancel my subscription. Then, what should I do? It was extremely difficult to find a way to communicate with someone on the Avira web page. You expose a lot of general information, but no email address for costumers who need to solve problems. You should indicate an email address on the first page, clearly visible and accesible. Furthermore, it should be possible to cancel a subscription by email as an alternative to the costumer account. Otherwise, as I have already explained, it can become impossible to cancel a subscription. 

Best regards,

Fredrik Sorstad
