India2Shop — assured gift not received

I got this call from India 2 shop that i am lucky customer who is assured a free gift if I purchase their deal of the day offer of 8252. I selected I Phone 7 for my assured gift and paid amount of 8252. I was told that my gift has been dispatched same day and provided tracking number. After 5 days I got my Deal of day offer but no sign of Apple I phone for which I had gone ahead and accepted their terms. After calling their help line, came to know that my I phone is stuck in Thier logistics and I have to pay GST and packing charges. This was never informed during the initial call. I ageed to pay the above payment. After 3-4 more follow ups, I was again up for a new suprise, I need now pay insurance as well. All this was never communicated. Only after following up they are coming up with new charges. Now I have paid almost 30% of amount. An item which was supposed to be free, ended up paying 30% of the amount.
Still I have not received my assured gift. It's been 3 weeks. Calling them daily but they do not have tracking number for such a valuable item costing 70000 but they gave me tracking number for item which costed 8252. Hahaha. Do not know what to do. Laugh or cry.
