AVG PC TuneUp wish to cancel subscription

Hello Chris.
We'd like to inform that automatic renewal has been canceled for AVG PC TuneUp 1 computer (1 year) subscription. We assure that you won't be charged for it.

I have just been informed that my AVG TuneUp expires on 1st June 2019.  I do not want to renew this.  How do I cancel this subscription?
Please reply to c.taylor12bop@gmail.com as my freeserve account no longer exists and I cannot change it in My Account.  Grrr!
