[Resolved]  Bigbasket.com — after waiting for 2 days bigbasket cancelled my order

I had placed an order on big basket which was suppsed to be delivered 2 days later, which is today. But, they cancelled the order today and asked me to reorder to the next available schedule. It is ridiculous for the customer to wait for 2 days and their order gets cancelled with some generic sms message. I have to wait for another 2 days but with what guarantee??
