WePay, Inc. WePay Steals Money! Redwood California

We have organizational status with Meetup.com.  We charge our members for events, movie tickets, luncheons, etc..  In the past, all credit card purchases were processed by PayPal.  Within the past several months, Meetup.com had apparently set up an account for our organization to accept donations and event processing fees.  Meetup set up this account with WePay, albeit without our permission.  However, according to WePay, we have never setup the account.  Due to the fact that we do not have an account with WePay, Meetup.com suggested to our group and to WePay, that WePay simply refund the incorrectly routed payments. 

WePay will not refund our funds unless we open an account with WePay.  Based on questionable ethics associated with WePay decision making and business practices, we have no interest in providing WePay with any confidential information.

WePay has threatened us to setup an account, or else WePay will refund each and every payment to our group's donors and purchasers of products, movie tickets, luncheons, etc.  WePay's threat is sort of like a Robin Hood scheme.  Collect fees and donations rerouted away from PayPal, then return same fees if we don't provide WePay with confidential information and agree to their rules.

Imagine if you sold something.  WePay would give your customer back their money, and allow your customer to keep the product they purchased from you.  It is wrong and illegal.  However WePay executives do not seem to think it is a problem.  Is this really extortion?
