Amazon India — Ptroduct delivery not on time /day

Address: Chennai

My ordered product suppose to delivered on Saturday and based on my availability on delivery address and order my new smart phone. first time i git msg saying -the delivery person unable to contact you post sowing out of delivery in Amazon App. due to that i have cancelled the product and cancelled other accessories also which was for my smart phone.

Next week also i order based on may availability at my home and the same think happening repeatedly don't know what to do...Its a worst experience.

Again i order phone accessories also. there is no meaning of these accessories if phone is not delivered.
