I can confirm that Sahana from Dell has helped me and I've received full refund from Dell. It is a bit unfortunate that it has to take it to the forum to get this issue resolved, but in the end, the issue does get resolved and I'm all good.
For anyone who wans to order from Dell Canada, be extremely careful! I have an order of the D3100 docking station with return request created on January 12, 2021 and tracking confirmed Dell received the return on January 18, 2021. Dell always claims the customer should receive the refund within 10 business days. Now it has been more than 10 business days and there's no refund processed. They outsource to India for this type of return request, and the agent (Mohammed Lukhman) who processed my return request will simply close the request, before a refund is issued. I had to request to create another service request, and after that everything just goes silent (i.e., they will ignore you and not reply to your email). I searched the forum and found a lot of similar stories (my experience is far from the worst). There are cases of it taking 3 MONTHS for someone to get a refund. In contract, Amazon would refund you the money as soon as they detect the item is shipped! Thanks, Ray
Taking forever to get refund (and Dell customer support will not reply)
