Hello There,

I work for an MNC and I got a gift card from my business owner. Because that could be only used on their country sites so I made them send some toys for my new born baby. Those were some around cost of 10k in rupees which included the insurance with delivery charge. Now my complaint is : Because these are non-customable things but still I got a call and was told by DHL representative that I need to pay 8.5k as a custom duty charge to make my parcel cleared and delivered to me.
I asked because its just a pack of my individual use and should not the custom charges applied on it because whenever I used different mailing service then I had not faced such a bad experience. Because these toys has some feelings attached so i am raising this issue as a complaint to you for why i need to pay more because it's already been insured and should have been delivered to me as I had paid the delivery charges. I am completely dissatisfied with the service and kindly let me know that how can i get my parcel delivered to me because I was told by their rep - its upto you that you can forget your parcel or pay 8.5k. I will never ever use these DHL services for any of my future use.
Another interesting thing that when I requested to send me the document - the one i received that had 7.5k as custom duty. I believe that DHL is making their customer fool and not willing to deliver the product. I am not sure if they want to sell it somewhere else or what. Please help.

Thank you,
