Bata India — I m complaining about refund I have not received yet

I ordered a pair of shoes but I received wrong product so I returned it. It's been 5 months they picked up wrong product and I am still contacting customer care but they reply me the same that the Payulink will be generated soon still I don't get any. I returned the product in January and this is April till now I haven't got a penny from them.. So I request that they should get arrested for fraud case or any action should be taken..
