If you paid with a credit card, your subscription is not recurring.
If you paid with PayPal, if you cancel or stop your recurring subscription, you can still use the service until your term expires.
To cancel recurring payments:
1. Log into PayPal.
2. In your list of transactions, click on the payment you made to BidSlammer.
3. Click "View Recurring Payment Details."
4. Where it says, "Status: Active," click "Active" and change it to "Cancel."
After these steps, you will be able to continue to have premium service until your term expires.
