Buffalo logistics and Fastway couriers

I have struggling with my parcel from Shein, after trying to track it for the longest of time. I was given an update that my parcel is in transit, and it is going to be delivered on Tuesday, 6 December 22. Upon following up again Today, I receive a very bad service from a call Centre agent Ann, the attitude was very bad, she was even telling me that I was given an incorrect information previously by her company. The correct information is the one that she has just gave me Today and the parcel will be delivered Today. She further told me that she does not understand my frustration, after I waited for a parcel for 2 months. Sorry Shein but this was my last order, I cannot fight with useless courier companies as if the clothes are free. Buffulo logistics and Fastway Couriers, you are really a disgrace to our society
