Bigbasket.com — poor delivery, refund and unauthorised reordering

I had placed an order bjpo[protected] which was delivered on 10/5/2020. Delivery agent simply threw all the grocery items on the ground in the parking lot of my apartment inspite of me clearly telling him too leave it outside my apartment.
Due to which i cancelled the order returned the items and requested for a refund.
But to my surprise, i got a message on 11/5/2020 that my order is reprocessed without my consent ejpro[protected], this was done without my consent and authorisation.
Again i called the customer care and cancelled the order and second time asked for refund, upon which i was assured by the call centre agent that it will be processed in 7-9 days but refused to provide me any reference no.

I found this behaviour suspicious so i sent a mail regarding the same to bigbasket on 11/5/2020 itself.
Bigbasket gave a reply to the mail on 17/5/20 saying that they have raised a new request for transferring the money and to wait for 7-9 days.

Then when i called the bigbasket customer care to enquire about it they told me there was no request for refund placed on 10/5 or 11/5, also though the time for replying the mail is the same day they were sorry that i recieved a reply after 5 days.
Now again they are asking me to wait for a refund.

Is this how you treat customers :
- delivering grocery on the road, even not waiting for the customer to collect it.
- reprocessing the customers orders without his consent
- not taking money transfer requests even after repeatedly asked by the customer.
- inspite of seeing of these issues of mishandling the custome by your call center agents ; the are asking me to wait more 10 days for recieving his own money and he simply has be at the mercy of your executives.

This is how you treat your customers?? You take pride on compensating customers for delays, how are you compesating for this??
