Unhappy client

Very easy process - all my info linked to my account so return was down in few steps!

I ordered 2 sets of 5 panties internationally - order placed end of July, and only 1 set arrived mid September. Asked for a refund of half the order that was not delivered. The half delivered did not fit well so was exchanged for a gift card (that took also few weeks but at least was completed). Now, almost 6 months after the initial order, multiple emails to customer service, the request is always elevated but never answered. Still waiting to get back what I paid for the product never delivered!
