Myntra.com — when you will take action

When will i get my refund??? Is it a joke going on??? Mantra has not yet been refunded my money. I have returned their product in december & still have not received refund. It's almost 2 months now & my money is with myntra. Why i have to wait for so long. They are lying that they have refunded the money which is wrong. My bank & google pay both have confirmed money is not credited in my bank account. I have called them so many times but they have not raised any complaint. Everytime they are telling me this is the first call they have received from me & they need 10 days to investigate. They are not doing anything i am sure. I want my koney
