MRF Tyres — where is the refund for cancelled order

I had cancelled an order on 13jan 2019, but still i haven't got credited to my account. And no response form customer care/service. Finally i got one call "sir, it takes time, u know it's a bank transaction",
I don't know which century you are living in.
You mrf has not yet paid.
And you are giving excuses by mails "it takes time i. E., 21days".

If it takes time to refund then how do you accept the payment within 5secs
