Universal Travels — Bus got canceled and not informed

At 14th Jan I booked a bus through universal travels via pondicherry to nagercoil at 7pm. Since 7pm I don't get any courtesy call from the travel agency so I reached the boarding point at 6.30 after I contact to bus drivers number it was switched off then I called some one of their agency ad asked about the status but he was saying the bus was canceled by morning itself and they saying that they was sen me regular message that bus was canceled but I didn't get any regular or a watsup messages belongs to bus canceled. If it's cancel by morning meaning they have to refund my money by that time itself but still I didn't get refund money from the bus agency and from today morning onwards I remind them for my refund still it was not happening seriously I'm very worried of this and it was a pathetic and worst service I have ever seen. Pls help for my refund ASAP
