Bisleri International — Order not delivered as per their delivery policy of 24 hours delivery

I have ordered 5- 20 litre water cans from bisleri app (BSLRE-003HY-768589).Paid money (as there is no COD option, which is supposed to be provided).Waited for 2days and there is no update in the app tried contacting customer care through their customer care number and mail provided in their website and app, but to my surprise no response from them.
Few days back got response through mail that they tried delivery and delivery failed(god knows why it got failed). Please make sure that you deliver your promise or just don't advertise about one day delivery, especially during summer it creates lot of problems for the customers. I hope someone responds to this complaint atleast and move things forward.
And please provide option to collect the security deposit back if we don't want to use your services anymore. Don't you think it is a kind of fraud that you are collecting money and not delivering the product and not letting us take our money back.
