[Resolved]  Ola Money — Cashback not credit after applied coupon successfully also no response from ola money after 15 days

I made a payment of Rs. 2000/- through Supr Daily App on 13/08/2021.
For that, I have to receive cashback into my OlaMoney active postapid+ account within 3 working days after applied the (OLA250) coupon successfully. but till now I haven't received any cashback.
So that I contact Supr Daily Support & they told me your (OLA250) coupon has been successfully applied, cashback credits within 3 working days to your OlaMoney active postapid+. so kindly talk to Ola money support for this issue.
till now I m not been able to communicate through the phone number which the company provides on the website, there is no form of communication through phone number.
I have been keeping trying to contact you on phone number past 15 days.
also, they even cannot resolve my problem with my mail.
I have sent the mail to all officers ( [protected]@zipcash.in, [protected]@zipcash.in, [protected]@olamoney.com, [protected]@olamoney.com,
grievance.[protected]@zipcash.in grievance, [protected]@zipcash, zip cash care, ola money support )
I have shared some screenshots of the mail.
