Mumbai Foreign Post Office — non delivery of package and no accountability

Address:

122011

An international package (Uj[protected]us) was received by the foreign post office on june 28th 2018. The same package has to be delivered to my residence in gurgaon through post office but despite the lapse of 3 months, the same has not been received. The local post has verbally said that no package is pending at their end and the foreign post offic is saying that the same is not at their end either. Hence both departments are not providing the clarity nor taking any responsibility.
