We have exactly followed by the Ebay return rules on the process, but the buyer suddenly upgrade the case without any notice. The buyerbreak the rules of Ebay company. 1. On 10. Mrz. the buyer did opened a return on Ebay. 2. On Mar 11th -13th We provide solutions to help buyers to actively solve the problem 3. On Mar 14th we offered the return adsress and return label first, and asked the buyer to return the goods, according to Ebay Platform rules. But the buyer has not provided a tracking number to us.We have not received the returned items yet. Taking into account the value of the project is relatively high, we have not confirmed that if article has come back, We have not received the returned items yet. So we can not provide a refund before the buyer provided a tracking number to us .And now we lose money and goods, but EBAY can not be regarded as seller's error, included in the bad account transactions. I hope you know. Help us remove these cases Believe that ebay is a fair and equitable platform, is a balance between the common interests of both sides, to seek common development platform So please help us Thank you very much for your help Looking forward to your reply.
