Parcel to be delivered from Khardah to Buroshiv Tala. Through tracking I come to it is in Kolkata AP Nsh on 03/06/2020. I have lodged a complain about it on 06/06/2020. Today it is 11/06/2020. Status is same. I am a regular user of speed post. Service is very good. Even I send many parcel to other states even in the red zones there is no problem in delivery. But why no action yet after complain yet. Not a single feedback. Please solve the matter.
