AVG Technologies - Subscription Renewal Reminder

Just got this email below. I have no idea how this got activated, nor on which machine/mobile this
happened. On top,  I already  have another active AVG account.
I don't want to pay for this and stop this subscription but the AVG portal is of no help.
Please  stop this.
Thx,
Dirk
