I have ordered 3 different products of above mentioned order numbers on 13th oct 17. These are suppose to be delivered on 14th oct 2017 as i am a prime customer.. Suddenly today i checked my order and found it cancelled without any information.. My amount of 926.50 is deducted on the same day. And now customer service agent is telling that these amount will be credited between 3-5 days.1st thing without any profit why should i hold my amount for 5 days and 2nd - due to this mistake of amazon/seller i lost my credibility.. Please confirm that how amazon in going to pay my credibility.
