Buffalo Logistics Bad Service

I wrote up on the service or non service of a refund from Buffalo on Hello Peter before. They emailed me asking me to 'complete the attached'. There isn't an actual attachment but a small blue written link you need to click on to open the form. Like myself, if you using your phone, you may not easily see it. I finally submitted with all necessary proof of the duplicate payment. They don't email to acknowledge receipt. They only do refund payments on a Friday, and it's been over a month (not including my wait since Jan 2024) and after sending another mail, I have STILL NOT received acknowledgement, nor my refund.
