I was given this info for a return and am unsure how to put it into a shipping label, specifically the street address:
Street Address:
District:
City: guangzhoushi
State/Province/Region: guangdongsheng
Address Line: Baiyun Qu jinshazhou unfonhuayuán nanqu 1 dong 501
Zip/Postal Code: 510000

I need to return wigs back to this company. First they were resisting me a refund trying to give me every excuse under the sun and basically told me I was keeping them. Then after countless emails or repeatedly asking for the return address they only offered a partial refund of which again after me rejecting that as not good enough, then did they send me this address. Can I check if the contact and address is legitimate?
And has anyone else who has sent refund to this address, have you received your refund?

The return label address is:
fosa
Lon hua qu da lang kie dao xin shi she qu yuan gao lu 2 hao
Ming jun gong ye yuan C dong 401
Shen zhen shi Guand dong sheng 518000

Will our postal service know where this goes or do I need this translated into English???
