If you have made a double payment, and you can see you have paid twice in the same month. You must have signed up twice. Please understand that we cannot withdraw payment from your account. We have no access to any of your personal payment information. in fact we cant even request paypal to withdraw money from your account. Only you can initiate a payment from your paypal account. and if you have signed up for a subscription payment, paypal will initiate a payment every month, until YOU or YAMS cancel the subscription. If a subscription payment fails several times, it will automatically be cancelled and hereafter you must subscribe to yams again by going to http://member.yamsonline.com

In your case you must have subscribed twice, Therefore 2 payments have been taken every month. 

We will go ahead and cancel the subscription and refund the payments or credit the payment, whichever we find most beneficial for you.
