Hello, i am returning a parcel from Aliexpress to the address given to me. Tracking number - RC500087558UA . The parcel reached the city of Guangzhou where it has already been waiting for 10 days for taxes to be paid, but I was not notified about how to pay them and what the amount should be. Should I pay for this or the person to whom I sent the parcel?
