Cex — Cex took my phone and did not paid me

Address: Thane, Maharashtra, 400705

Website: In.webuy.com

I sold my iphone 6 plus to CEX in thane, mumbai. They gave me a receipt saying they will transfer my money to my bank account Its been 12 days now but no money has been credited to my account yet. Since last 5 days the only answer i get is the money has been transfered to my bank account and it will reflect any minute. I have also contacted my bank regarding the same but my bank says there is no such transaction waiting for clearance. I have also emailed the cex customer care but they are also not helpful. I am going to write a formal complaint to the police station regarding this and take this up legally.
