Myntra.com — problem in refund

I had ordered some cloth on 24th june 2019, order no: 111323669083250836503 and i returned some items from my order because its was not upto my expectation i have not yet got my refund of that order. I contacted to customer services. And they provided the reference number which is denied by the bank. Both are blaming each other without solving my dispute. I want my money back so kindly command them to refund my money soon.
