PMC Jewellery - Delivery never received.

I Have never received my delivery from PMC Jewellery. They sent me the below - Tracking number: YT***=BUFZA***YQ but Buffalo never delivered. When I go on Buffalo tracking - it indicates closed - package discarded.

Surely responsibility still lies with PMC to return my funds as I never got the delivery, despite many many emails to them and Buffalo. I did not choose Buffalo - PMC did. Like others I believe PMC and Buffalo are **** artists now. I will repost here until I get my funds back from PMC OR the earrings. Additionally, I have posted my dissatisfied reviews on PMC Site but it does not appear. I am a very disappointed pensioner.
