Item not even close to as advertised

[fathomx6]

I need advice...ordered a 1-300X monoscope from a US address, payed with paypal.  It took a while to arrive and turned out to be shipped from China.  Wasn't nearly anything close to what was advertised.  Much smaller unit and marked 10-30X not 300X.  

Contacted the seller to complain and asked to return for refund.  Their replies did not address my question and this went on with their latest reply that they sent the correct item, could not return and would not refund.

Contacted paypal and they said seller said return to China and I would receive refund. I'm thinking spending $30 postage to return and then not receiving refund is in my future.

My question is, if I dispute through my CC and they take the funds back it will be from paypal.  Will that affect my paypal account? Could paypal punish me or pursue me to recapture funds?

In the event of a dispute you need to bear in mind possible return trackable costs before you buy from that seller / item / country because....

Paypal state this >>
PayPal is not obliged to reimburse you for any costs that you incur to comply with any of PayPal’s requests for cooperation for the purpose of resolving the problem (including, without limitation, costs that you incur to return a SNAD item to the Payment Recipient or another party as PayPal requests), although sometimes it may reimburse these costs.

Although they will compensate you for some of the cost if you have activated this at some point before you made that transaction.

You also have the right and option to do a chargeback via your card issuer instead of a Paypal dispute if you funded your Paypal payment via a credit card.
