Awb[protected]
Were supposed to be delivered on 22nd june.
Its been about 20 days and fedex is not responding at all.
They are asking me to pick up my parcels from guwahati which is a totally different state from the original destination of my parcel mizoram. It is not possible to pick up my parcels from guwahati because i live in another state.
They keep giving excuses about total lockdown in mizoram, but lockdown was lifted since many days ago.
They refuse to pick up calls and not taking responsibility for my missing parcels.
They gave me invalid phone number to call for inquiry about my parcels. I have been calling them for the past 10 days..
Please help..
