[Resolved]  India Post — parcel not delivered, misplaced the parcel and straight away says to file a complaint

Address:

Thane, Maharashtra, 401107

I ordered one parcel from aliexpress and the same was successfully came to mumbai mira road post office on 4th jan, 2020.
But in my tracking it was showing the parcel cannot delivered due to insufficient address in spite of providing the correct address, so i went direct to the post office which is just 1km away from my place.
After going there on 6th jan, 2020 the postman & supervisor started to find my parcel, but after waiting for 30mins there answer is we cannot locate your product, if we will get that product we will contact you by the evening or next day, i said ok and left.
After 3 days i was not contacted neither the parcel arrived, again on 11th jan, 2020 i went to the post office and the parcel again started to find the parcel and latter said we cannot locate your product it must have misplaced or lost. So i told them i want to file a complaint to your post office regarding this, then they straight away said you go and file a complaint to aliexpress that mira road post office cannot locate your product so provide me a refund.

I said i will do that but the fault is yours so i will first file a complaint here.
But they said we won't take any complaint you go and file the complaint at head office of india post.

What kind of attitude is this at first they themselves misplaced/ lost/ stolen the product and now they are saying we won't take the complaint.

Playing with public's hard earned money is what india post job is?

I need my parcel to be delivered or else provide me the money i lost.
