Dolphin Travels — money was not given back after cancellation

They have not returned my money as i have booked a seat on 7th of november but even today no one has given back the money and no one are picking up the the phones and on the same the travels told that you will be getting back but even after 15 days they haven't, please look into it. Looks no one are responsible for the company and if the travels is not capable of doing these things they should quit or leave instead of harassing people mentally and the sudden cancellation of bus also takes place, don't know why the travels are doing
