Order Cancelled Not Refunding

I ordered earbuds from telemart and did the advance payment. Now, my order is not being processed, there is no helpline where I can complaint or even call. This is pathetic, it is a scam . on whatsapp after every two or three days with a reply "please wait Sir" or "We are Sorry " I cancelled the order that they imediately did and now its been approx 2 month I didn' t receive any refund
