eBay Charged Seller Fees Twice from Debit Card and Customer Care is Ignoring all responses

[tagnext]

My eBay seller fees was charged twice as follows:

01/05/2017 IIN/EBAY INDIA /20170429235259 Dr. 606.90

17/05/2017 IPS DB _04/29/2016_4662_EBAY I Dr. 606.90

I had called on the ebay customer care phone 14 days back, executive promised a response within 48-72 hours and didn't receive any response from the ebay side yet.

Please revert or credit to my ebay account immediately.
