Xpressbees Logistics — Out for delivery - wrong pincode - rescheduled delivery

Since no proper response from the Customer Care email service.
Even i tried cald many times from Mar 21st to till date, but Customer executives are without proper information, just simply wasting my time on call.
Hence escalating my issue to you.
XXXXXXXXXXX is my AWB number, my product shipped from Punjab on Mar 13 and reached the final delivery station on Mar 18th, till now i have not received my product. Whenever i cald customer executive they just say Sorry and arrange the delivery for tomorrow. There were many tomorrows passed but still my product was not received. Somehow today when I fought with them, they connected my call with the final delivery station person, and he confirmed no delivery service to the final delivery address.
So it means Customer Care executives without proper knowledge and information simply wasting my time and giving false promises on delivery schedules and wrong information.

Moreover, if there is no delivery service to my location, how will the xpressbees taken order from my customer (FirstCry).
Even that final delivery station person did not call me to inform me that my product is at which place and that can be delivered or not. Even Xpressbees application is also not good, they are not sharing the exact location where the product exists and their contact details. After the product out for delivery, xpressbess not shared delivery guy contact details, even that delivery guy did not call me to inform whether he can be delivered or not, he simply put incorrect pincode and stop delivery.

Please let me know how I can escalate this issue to a higher level, so that this issue may not repeated in future for anyone.
