Paulo Travels — I am complaining about seat change

I reserved three sleeper seats on 25th september 2023 in paolo travel bus 6.40 from kudal to mumbai paying 5902/- through paytm. Bus was two hours late, nobody was picking a phone and no proper message. As bus arrived we saw seats given to us were seaters and not sleepers. I was shocked. This is cheating with passengers. Take charge of seater seat and refund my extra charge.
