No attention to detail on customer orders

I paid Buffalo Logistics for my Shein parcel on the 30th of April and since then I have made a lot of calls and sent proof of payment maybe 30 times and the agents all say they see my proof of payment. Last Friday, they said my parcel will be delivered on Monday. Today it is Thursday and when I called again I was told that my parcel was going to be returned to China. Imagine the shock and frustration after so many of my attempts to get my parcel. I was then told to request for a refund when I don't want a refund but my parcel. I am not happy really about the way in which Buffalo has handled my issue. Lack of empathy and not looking properly at what the system has before they decide to ship orders back.
