report a buyer Not working

[queenslander-one]

I have a buyer who claimed at First overcharged Postage at $7.80 in fact Paid for $1.40 showed my Paypal reciept & Invoice via scan and backed down then reckoned item was not described after viewing multiple scans and would be returning it. I agreed as per my return rules 3 days for refund postage at Buyers cost. Nothing returned in a Month now see how Trashed my DSR's. Trying to use Ebay's Report a Buyer cannot get it to work. Says come back in 15 Mins. 15 Mins later the same been trying for a week.   Why should I suffer this Pest messing up my DSR's for $2.40. $1.00 item & $1.40 postage. Any Ideas.
