India Post — too much delay in delivery

Sir, i had purchased a product from online shopping site (Tomtop) having to make online payment on 16-08-17. Which was shipped on 18-08-17 through china post whose tracking number was rs[protected]cn. When i tracked time to time then i found that my parcel was reached india on 28-08-17 and last update was {india, kolkata foreign lcao, send item to domestic location (Inb), air, crc (Non-td) kolkata rms
[protected], 16:56}. There is no any updates after that. I think that its meaning is that my parcel has been handed over to india post for further delivery process. But sir, there is no any updates after 09-09-17 on site of india post. So i am worried. So please clear that my parcel has been handed over to india post or not? And did my parcel shipped.? When will it deliver to me. Please send me latest update about my parcel.
