Paytm — Cash refund problem

Address:	380007
Website:	paytm.in

Hi there i have purchased a stability ball from paytm. Purchase id is [protected]. The order haf been cancelled due to insuficient stock. So they have to give refund my money back, because i have paid online for that ball and after 2 weeka they are telling they have refunded me in my bank account. But i did not get any rupees yet. When i complaint about this to paytm they are just sending mail in whiche they are mentioning that they will resolve it within 2 days from last week. They are not wven picking up my phone.
