[MVD01]

Long story short, I did a MEB on my mate's 2 yr old Amazon account with a long list of orders for a CPU (which is externally visible) sold by a third party. The seller was yapping about launching an investigation and checking CCTV, weight etc. so I just contacted Amazon Customer Service, who connected me with a specialist who instantly issued the refund (amount was £500). The seller contacted me and said that they've appealed to Amazon, since "I didn't return the item, and we have proof of you recieving it". Should I be worried about Amazon taking the refund back?

Also, they reproted me to Action Fraud but I don't really care about that.
