Big Basket — Repeated delivery failures- Dishonouring of Delivery commitments and items

Big Basket is so far the worst services company that I have experienced. They have failed to live up to their delivery commitments (in terms of the delivery time and items delivered) for consecutively 5 times in a row now. Their customer support is the lamest of all and can't do much apart from apologizing on call or sending the same apology email over and over again from different IDs. Without a miss, they have failed to deliver my order on the same day and are instantly ready with excuses such as operational issues, delivery boy going to incorrect address, vehicle breakdown etc. Even if they make on time, some of the items are always missing and customer only comes to know when the delivery boy shows up. This is extremely frustrating and one realizes that Big Basket has no regards for their customer's time, needs and experience.
