I didnt sell a service that dont work and second i cant even refund its blocked he just have to wait for the dispute to be closed
Sure np
Surely if everything was working perfectly then we wouldn't be having a disgruntled customer here... would we?
Plus you should have explained to him what was at hand... keeping quiet or not giving any details makes the other party to start guessing or thinking they have been scammed and i wouldn't blame them for opening up a scam accusation.
Anyway i just hope you resolve the issue and the outcomes are satisfactory to both parties. For now the tag and flag will remain until i can confirm that no one has been scammed.
