Amazon - Package not delivered

I ordered a study table from amazon on **th march **** and the delivery date assigned was **th march. But on the night of **th march(after * pm) they extended the delivery date to **th march. I tried to contact the customer support but I got no response. On **th march I got a call from amazon(because of the email I wrote to them) and they said to cancel the order and place a new order.I waited for ** days and the delivery date for new order was ** April(** days from ** march). I am a student and my study is adversely affected by this. This has harassed me mentally and caused a lot of loss to my study which in turn has added to my mental trauma
