Hey guys!

Update: I just received my quadcopter today!  

The package was initially retained by Bangalore Customs and this was the update from them - "Retention reason : Awaiting proof of purchase/value from addressee"
I contacted one of the Assistant Commissioner of Bangalore customs and enquired what is required for them to process the package. They requested for a invoice.
 
I had received a invoice from sp4mm3r at the time of purchase. Luckily sp4mm3r had reduce the price in the invoice to half of the actual price I had paid.
The invoice delibetraly has lower pirce value to reduce customs duties.

However when I visited the local Customs post office to submit the invoice I was asked to pay Rs. 964 as customs duties/taxes for importing. I had to pay this at the time of delivery.

They then processed the package to my local aera post office and I just received it today. Paid extra Rs. 964 for customs, but finally was content having the package after hearing about so many regulations duanting the delivery of such packages.

A happy ending finally!  

Congratulation!!

That's way to much you paid for the customs, if you might have not contacted personally it might have been less

Congo anyways

Hello everybody! I ordered a trantula x6 on 27th may from sp4mm3r . They dispatched it on 3rd june and further details of tracking are mentioned in the below picture. I want to know that should I contact my local post office as the parcel had been released by customs on 30th june, or should I simply wait?

Don't worry! if it was released you should have it soon
