Yes, you can. When you subscribe, you pay a monthly fee in advance. So if you subscribe on 4 February, the services will last until 3 March. To cancel:
1) Login to your PetGP account at https://pet-gp.co.uk/
2) Once logged in, you will land on the Account page. On the left hand side of the screen, you will see a “My Subscriptions” option. Click on it.
3) You will see 2 boxes: Free Membership and Premium Membership (this one will say “Active”). Click on the “Switch to Free” option.
4) This will make you a Free Member when your premium membership runs out (one month from the last date you paid the subscription charge). You will pay no further charges
In the example above, regardless of when you cancel the subscription will last until 3 March as you have already paid for it.
