Purchased robot mower on Amazon last Friday. Said it would be delivered Monday. Got e mail.from.DHL saying it has been delivered. Checked everywhere, no package. Contacted seller, DHL and Amazon. Apparently it was a tracking number issue , once a new tracking number was issued the mower would be sent out. I said I think it's all a scam and want my money back. Amazon assured me I'd get my money back, the company said they will refund it within 3 to 5 days. Ill keep my fingers crossed.
