Ninth Avenue — Not refunding my money

I Placed Order With Ninth Avenue For L'Oreal Paris Colour Riche Lipstick Number 630, Beige On 1st March (ORDER IN-NA#12920). After Multiple Follow Ups With Them, Since My Order Was Not Delivered, I Asked Them To Process Refund For The Same On 13th May. On 27th May I Got An Email From Their Customer Support Stating That They Have Initiated The Refund And I Would Get My Refund Amount In 7-10 Days. However, Till Date I Haven’t Got My Amount Back. I Sent Them Multiple Follow Up Emails Asking For My Amount In July But They Are Saying That They Cancelled My Order On 3rd June And Initiated Refund. They Are Asking Me To Follow Up For Refund With Ccavenue Which Was I Believe The Payment Gateway For Ninth Avenue. Their Phone Number Mentioned On The Website Does Not Exist. And So Far I Haven’t Received My Refund.
