Buffalo corrie has bad service

I have a parcel from Shein with tracking number BUFZA***YQ that failed to be delivered yesterday by Buffslo corrier. I changed phone number however i tried phoning them to update my new phone number from since Monday this week but the phone number provided on their Buffalo page just ring with no answer then I send them emails and watsapp but no respond. I send then my new number they can be able to reach me but they not using it instead they documented on my Shein tracking parcel page that parcel returned due to no phone answering. Now they want to charge me extra money for the rearangement of delivery. To my surprise when did that started to charge extra money where as their communication is very bad.

It is December I need money and they want extra money from me after I paid a lot of customs money. The next thing they will be informing me that my parcel is shipped back to Shein what kind of abuse is that. They don't communicate well and they don't read emails and watsapp but they very good in informing you and when you respond back they don't take or consider your comments.
