Myntra.com — didn't get my refund back 2 weeks

It's almost 2 weeks and still I haven't got my refund back I ordered 2 bags and key chain and paid online but afterwards I cancelled 2 items but ordered only 1 item (bagpack) yes my money got deducted .. I asked customers care services they told my money will be refunded by 22 may 19.. still didn't got my refund I emailed them 5-9 times but as usual silence no reply and after that my contact us was showing an internal error... don't know what game they are playing ... I warned them I will file a legal complaint against them But no refund and reply highly disappointed 😠😠
