Myflowerapp — Their payment gateway issue-refund issue, their service and app issue

Website:

myflowerapp.com

They are not initiaitng my refund of 1106INR. At first it was stated that -

Cake will be delivered.
Then they said no after an hour.
Then i cancelled it. Then they quoted - refund will be done in less than a week.

It is now more than 2 weeks ans i tried to contact.
I am now told refund is getting error. They are facing payment gateway issue.

Now to get my ampunt back, i have to order and need to order more coz that ordered cake cannot be delivered for 500kg. So i have to order 1kg... So instead of refund, i ended up ordering.

I am annoyed coz of bad customer service. The alias name or real name - i dont know - Kavya - not good, shared thrice incorrect information, did not provide any resolution and made more sales through me by extra payment.
She ignored me multiple times.

I want to complaint againt app and its owner specially
