Consumer Redressal

There is an institute called Hari technologies opposite home town in marthahalli. I joined for selenium and paid 8500 rupees. It is 45 days course. I attended only 4 days and because the trainer was very rude I asked for a refund. The Md said that he will transfer the amount to my bank account. So I gave my account details. Its been more than 10 days. He is not picking my calls and there is no proper response. Pls solve this. I need the money
