I heard a lot of bad stuff about RMA-ing stuff with Ebuyer. I just did it 3 days ago and It was quick and easy.
RMA Request Opened - 18 Nov
Package Sent - 21 Nov (Can't be arsed to send the package on a Saturday)
Package Received - 24 Nov 10:57 (Time for email reception, more like they got it earlier but processed later)
Product tested/found faulty - 24 Nov 10:59
Replacement ordered, but no stock - 24 Nov 11:03
Order dispatched - 24 Nov 19:28 (stock just arrived?)
Expected delivery date - 25 Nov
4 days turnaround wasn't bad at all. Now just let me try and claim the return postage.
