First, bear in mind that if you do not normally maintain a balance of funds in your PayPal account, it would be normal to see two transactions in your PayPal History for each subscription payment: one where PayPal taps your chosen funding source to bring up your PayPal account balance enough to cover the payment, and another where they actually send those funds to us as a subscription payment.
If you already have an active subscription with E-junkie, normally our system will not let you create another subscription for the same account. However, if PayPal does not immediately notify us of your new subscription due to some delay at their end, then during that delay it may be possible for you to attempt subscribing again and thereby wind up creating two subscriptions.
In that case, you should go E-junkie Seller Admin > Manage Seller Account > View Account Summary and note your current Subscription ID (a long number starting with "S-") to identify which subscription is actually linked to your E-junkie account. Then, click here to log into your PayPal account and find subscriptions you've set up for Sine Info Ventures Pvt. Ltd. (E-junkie's parent company). You can then cancel the subscription which does not match the Subscription ID you'd noted from your E-junkie Account Summary. This PayPal help page explains in more detail how to find and cancel a subscription from their end.
Please contact us with your canceled Subscription ID and E-junkie Login E-mail, and we'll be glad to refund your duplicate payment(s).
