Universal Travels — provide me a full refund

[4:01 pm, 3/21/2020] spin durai: hello mobikwik customer care,
I have booked two bus tickets to travel from chennai to mayiladuthurai on 20th march 2020 in universe bus (Ubs) through mobikwik. My ticket pnr is 45et2shb, operator pnr is ubs266635 and bus operator i'd is [protected].

I got message from the bus travels that my bus got cancelled and alternative bus will be arranged, but there was no contact number specified in that message. So i tried calling bus customer care number which is not working and after googling for hours, i got another number of the travels and it is busy for more than 1 hours. After continously trying for 1 hour, finally a person attended the call and states that my new alloted bus's driver number will be sent to you shortly. And by 10.30p. M i have received a message containing new bus's driver number and bus timing to board at chennai guindy by 11p. M. Despite of this last minute confirmation, i started to guindy from my home in guduvancherry which is 30 kms far from the boarding point with my wife and 2 kids (2 month new born baby & 3 year old baby) and i started to contact bus driver on my way, but he was constantly rejecting my calls. I have reached the boarding point by 11.15 p. M & was still trying to contact the driver. And i have waited for more than 45 minutes in my boarding point till 12 a. M and i lost hope about bus picking us and i was no longer ready to put my family in risk waiting at bus boarding point in mid night with my wife and 2 kids waiting for response from the unresponsive bus driver. So i decided to leave to my home, despite of my situation that needs to travel to my home town. By the time i have reached home, i am getting call from the driver stating bus is waiting for me in my boarding point (12.45 a. M). And i cannot travel back 30 kms again to catch this bus and put my family in risk again. I am very unhappy and fed up for the inconvenience caused by the bus travels yesterday. I would request you to take appropriate action against the bus travels and provide me a full refund.
