I never thought amazon will go from best to worst in terms of delivery and return.I have given up on my refund.Pathetic customer service especially chat, they don't understand they can't talk decently, need training or loose your customers ..I was told " What do you mean by tentative, we can't help if you can't give exact date" when I was already telling in the same chat what has happened multiple times ....this is the way they treat when the customer is dealing for like 5th time explaining the issue over and over. Mind here the issue was accepted and apologized in the first chat, however later when I connected again to check the grievance status it was treated as a new issue and later told that they can't help me.Again I'm prime customer shopped for more than Rs 10000 and just returned few items.The issue was passed over to like 4 chat agents in the same chat due to not understanding and finally was connected to a call where I had to explain from the start.Thankfully he understood within minutes.The chat guy( would love to name him) could not find my grievance raised in the system which later was found out by other customer support guy who called me ..I have wasted more than 3+ hours to get my hard earned money.The system is useless too , they expect to remember the exact date and time but the system can't do so.The system says the item is yet to be picked when it's picked up a week ago.Is this really amazon??
