Kpn Travels — question for safety and refund

Ticket was booked for non-ac sleeper at 11.15 bus from periyar bus stand madurai on 17.9 2017 (Ticket number [protected]). But your company has sent volvo semi sleeper instead of non-ac sleeper. Also, the driver found a problem in the bus in madurai. Vehicle number tn 30 bf 0259. But the bus was kept in a petrol bunk in the four way for 5 hours (From 12 am to 5 am) without informing this problem to passengers. My daughter called me to pick up from that place. I went there by my car and returned with my daughter to home. I have informed this over phone to your contact number[protected] on monday (17.09-2017). Now i want you to refund ticket amount. For this, you have informed to contact redbus. We have also booked a complaint in redbus. But you have replied to redbus that the bus was reached madurai, there is no problem. I request you to sent a mail to redbus that the bus tn30 bf 0259 was not run at that time to chennai. I have the proof for that. Otherwise sent the refund to the bank account.
