[Resolved]  Indigo Airlines — cheating customer - refund not processed

I had cancelled an international indigo flight (Singapore to lucknow) on 7th dec 2019 and there was an amount of 293 sgd to be refunded.
Refund takes 7-10 working days but my amount was not refunded until 9th jan 2020, hence i called indigo customer care again. The customer care executive mentioned there was some issue from indigo side and the refund was not initiated (Problem was never mentioned). The executive initiated the refund on 9th jan 2020 and said to wait for 7-10 working days.
I waited and i called again customer care on 28th jan 2020. The customer care executive 'sharan' took some time to fetch basic details about my itinerary and cancellation and then said from their side there is no problem, refund is already processed and go check with the bank. I mean seriously is it the customer's responsibility to go and check with the bank about the refund for which i do not have any reference number as well.
I disconnected the call and called the customer care again. Then the customer executive 'atul' picks up the call and said he can see there was some error from indigo side and the refund was not initiated on 9th jan 2020 but it is processed now (28th jan 2020).
I have to wait again for 7-10 working days.
This is the way of troubling customer and giving them wrong information about the refund and hiding the errors from indigo.
They are not able to initiate a normal refund.
When i asked atul to provide me the reference number of refund or proof that refund is initiated, then he said they do not have any such information and cannot provide.
Is this some kind of manual paper work going on that do not have this information.
I am really really really disappointed and irritated when i have to chases for my own money.
I have no idea even after waiting for 7-10 working days again will i get my amount or not.
