Travel Triangle — Issue with refund

I had booked my holiday booking to Kerala with travels ie., Oio travel tied-up with travel triangle bearing ID No: 10207227. I have paid the initial payment of Rs. 6060/- on 6.01.2023 as a part payment.
I had not received my hotel voucher after part payment. The representative of the travel agency later informed that the hotel mentioned in the quotation is unavailable and the alternative option was provided. The same was not liked my me and my husband. When asked for equivalent other hotel, same was not provided in further coarse of time.
Hence I have informed the representative to cancel my booking over phone several times and to the travel triangle representative several times over phone and through e-mail. But it is regretted to inform that my refund is not yet processed.
It is very ignorant being tied-up to a reputed company like travel triangle to cheat customer this way.
It is requested to refund the total amount of Rs. 6060/- to the source immediately.
