Ferns N Petals — complaint regarding customer care and order

I am writing this to you when i had loosen all my hopes and that probably last order from your company.
My name is manu abhishek and i ordered a product for my sister's birthday on 19.10.2019 which was giving an optional date to be delivered by 20.10.2019 but since i had a good experience with your delivery and decency i made it for the specific date of her birthday that was 21.10.2019 and here what i did blunder trusting you.
Later the product was in the desired hub that is ghaziabad from 20.10.2019 itself as confirmed by customer care but they failed to deliver that on the date.
I called customer care and literally requested them to get it delivered as its a sister's birthday and that will be of no use to me if that is getting delivered later.
In morning they can't commit but they will try. This was a shock for me as ferns n petals never delay (So far i know) and they keep on repeating that it may be delayed and taking a cover of the policy. I respectfully said i'm that fine with your policy but please try to get this delivered to date which was committed while placing the order but that doesn't help.
I kept my patience whole day and again called in evening around 7 and got same answer. As i was not satisfied i asked for a supervisor thinking that they may help in other way so at least i can give my sister any gift and the birthday won't be spoiled from my side at least and here once again i trusted and that was thrashed
I would like to take the name mr. Sahil who is working as floor supervisor attended me and gave the same response.
What you can expect when you ask for escalation? Minimum same answer in a different way or at least a person who can handle you well and help you to calm down?
But things were opposite to me while talking to this gentleman. He was so casual, no empathy as well as commutation skills were pathetic as he switch to hindi by his own.
In the meantime he was explaining saying me "dekho" and i agree and apologize that by seeing this unprofessionalism of his i lost my patience and was literally started shouting. Then i asked for manager as i was hell lot of pissed by this approach and surprisingly he said that he is the final authority available without any asst. Manager or manager.
Like seriously if this is the way you people are handling customer service then trust you will be in deep trouble and you all are wasting all the efforts of mr. Vikaas gutgutia which he is putting for this company since 1994.
I never seen this kind of customer service ever and leave the order this will be a reason that i will never come back to you again.
May be you also will be least bothered about a customer leaving you like me but for me values are important which can't be compensated.
Most humbly i am requesting that please go through the call recording of mine in the evening.

Its really disheartening that i have to reach you for this but that is required now as such approach of supervisor can't be tolerated and that will lend in destruction of any organization.

I would request you please see this as this is critical.
