My parcel from AliExpress Tracking# RV[protected]CN has reached the Kolkata India post office by 10/06/19 and stuck there from then, the tracking also shows the same from the time it was received in that place it has not been sent for me this is very bad service shame to see the major post service of our country to be having these many complaints. I want my parcel to be delivered to me, stop looting the public.
