Bulkitemsbuy.com — product delivery was cancelled but money not refunded

I ordered Xiaomi Mi A1 on 09/27/2017 but the product was never delivered to me. I emailed you to refund the money but it has not yet been refunded. Its been about ten months and you have not refunded my money and now you guys are not responding to my calls. Please refund my money back.

I have attached the payment invoice with this complaint.
