Amazon India — courier service is misleading me about my product

Address:

171213

Sir a book a product on october 10 by making payments in advance.
Gati courier service is not sending my product at my door. But amazon had assured me for my product to be available at 171213. I was regulary getting my product in my address since past three years. But this time this third class courier service is misleading me. Last yime i had to travel 70km to take my product from gati courier company office by spend in 1500rupees as taxi charges. Plz solve my problem immediately.
If amazon continue to be with this gati courier service then i must say bye bye to amazon.
Plz solve my issue.
