Really bad service, bad communication

I ordered some cutting disks for use in my workshop on 11 October 2023. Everything confirmed etc. Then Buffalo Courier tracking, but the items never arrived. I emailed, called etc. Everytime they follow up and send me the tracking link again. Eventually on on 26 January 2024 I send them email to cancel. They then informed me that the Courier informed them the package was lost. On 31 January they ask for Bank confirmation to refund the purchase. This was provided, and it is now 7 Feb and still no refund.
