Cancel GeoZilla Subscription

I am writing regarding an unwanted Geozilla subscription that I mistakenly activated and have been unable to cancel since around 8 August. I have been charged about £46 in total so far. I contacted Geozilla customer support and they explained how to cancel, but despite following all the instructions, I still cannot find where the subscription is actually set up. I have checked Apple Pay, PayPal and Geozilla itself, but there is no clear subscription entry I can cancel. I live in the UK and would like this ongoing subscription to be stopped immediately and the charges that were taken in error to be refunded, as I did not intend to continue using this service and have been unable to locate or manage the subscription despite trying all the suggested methods.
