My Flower Tree — order not delivered and payment not returned

Address:

New Delhi, Delhi

Order number 629922 which wad to be delivered on 14th feb between 6am to 9 pm, did not get delivered. I also payed a surplus charge for delivery on this day.
They received my call once and straightaway told me that refund can not be done even if my order can not be delivered today and cut the phone immediately. I tried reaching out to them again but there was no response on the customer care and they are simply not contactable through any channel. They ruined my day and are completely fraudsters.
