Unusual buyer's activity - 17 orders with different delivery addresses

Hello everyone,

I have just noticed unusual activity. The customer placed 17 orders for the same item, but with different delivery addresses and names in the 2nd line of the address (all addresses are business properties - random units, shops etc.). So either the Customer’s account has been compromised or it is the competitive seller. It would be impossible that the same person will be at 17 different locations at the same time to accept the delivery, therefore, even if I will ship these order tracked and signed for I would not be able to defend A to Z cases because the signature will not match buyer’s name. I have tried to contact Seller “Support” Reps, but I have been informed that the only action I can take is to report the buyer and in case if A to Z will be filled for these orders I will have opportunity to represent myself
