My tar book issued by IMEI was picked by Delhivery on 25th march and reached Chennai hub on 27 march. its been 10 days since it arrived there still the parcel hasn't left the Chennai hub. Even after multiple queries through their site(the only option), no response from Delhivery team. there is no customer care number to contact them.
