PayPal took {$76.00}, egregiously and unnecessarily, from my bank account on XX/XX/19 without notice or permission. 
They violated my trust, & fiduciary duty by acting to my detriment when all that was necessary to satisfy the requested refund to a Buyer {$1.00}. Using the balance in my PayPal account + {$1.00} the total amount of refund would be available to complete a refund. 

The amount of {$1.00} was debited from my PayPal account and they failed to refund this amount, which is not due to XXXX, because the transaction was canceled. 

PayPal failed and refused to use the monies residing in my account under their control to first pay the refund amount and then secure the {$1.00} from my bank account to create the total refund. 

This manipulation of {$1.00} knowingly and deliberately caused the balance in my PayPal Account to fall below the refunded amount to Buyer ( I am the seller ). Pay Pal relies on this short of {$1.00} to take all of the money {$76.00} from my bank instead of simply {$1.00}. 

PayPal refused to act in my best interest to secure the refund of {$1.00} which should automatically be reversed at time of cancellation of the sale. Instead XXXX and PayPal work together to create the circumstance to which PayPal claims they are entitled. This tactic is designed to the detriment of the Consumer. 

Keep in mind XXXX and PayPal are still sister companies. The actions of one can be construed as the actions of the other. They act in concert and to the benefit of one another. PayPal maintains a monopoly created and continued by XXXX which demands PayPal manage all funds from buyers and sellers. There is no other choice-all funds must get processed the through PayPal. 

This self serving egregious behavior is designed to disadvantage the Seller. 
After I ( Seller ) canceled a sale all attendant charged should be reversed without delay. They delay IS a deliberate egregious act on the part of XXXX. 

PayPal had no problem taking {$10.00} for postage which was never used and also canceled. To this day this amount has not been refunded by XXXX  or PayPal. I requested PayPal file a dispute for {$10.00} ( postage ). They refused. I asked they contact XXXX with my concern much the same as a credit card company would be asked to file a disputed charge for merchandise not received. Again they refused. 

All acts complained of are in fact egregious acts designed to take advantage of the consumer which allowing PayPal to control XXXX of dollars at any given time. Money which belongs to others is used for their gain and to the detriment of the consumer they are supposed to serve. 

PayPal claims their " Terms and Conditions '' allows them to take the entire sum from a connected bank account if the PayPal balance falls below the amount of refund even by one XXXX. This allows then to use the same tactic if the amount were {$700.00}. or {$7000.00}. to which PayPal claims a right even though the entire issue can be remedied with a charge of {$1.00}. There is something very wrong here. 

How is this different than what banks would do by charging overdraft fees to client accounts based on their manipulation of charges, checks, and debits. Banks were were fined for their egregious acts. PayPal should be fined and penalized as well. 

Their acts are egregious by design and it is under their control that they take funds to which I claim they had no need or permission. 

In Summary : If PayPal took only the {$1.00} which they claim has not yet been refunded by XXXX ( their sister company ) they would have ample funds to refund the Buyer in full for the purchase I refunded to him. 
Please Note : On the date PayPal removed {$76.00} from my bank account the balance in my Pay Pal Account exceeded {$140.00}.
