The item the seller sent me was defective, so I requested a return on eBay. The seller offered me a partial refund, which I accepted. However, the refund was not issued within the timeframe specified by eBay, so I opened a case. eBay promised a response within 48 hours, but I haven't heard anything from them for 20 days now. What should I do in this situation?

@ala2200 the lovely @alena@ebay can take a look in your account and check what's causing the problem. Thanks, Alena
