I had a buyer offer a Best Offer which I accepted. Took 4 days for them to reply to my invoices and messages about the sale. They then proceeded to stall payment, saying it would maybe be tomorrow or definitely by the weekend etc. I sent it to resolution after 10 days and they then claimed to have put money into my bank account, told me all their family problems etc etc. No money in my bank account. I cancelled transaction. Is it even worth submitting negative feedback or is it just inviting them to send negative feedback back? What do you think?
