Yes i had the same issue with this seller marc.maurin on amazon.
I ordered 1tb Samsung Evo 850 SSD £204.04 on 10 July
Delivery window was right up til today 29 July.
I just phoned amazon, they have began processing the refund which takes 5-7 days dependent on my bank apparently.
Here was the only site i could find information on this fraudster, so want to post again so that others don't get defrauded by this crook / find out sooner then i did, i waited 19 days for my parcel and now have to re-order.
Cheers!
