Cordelia cruisesWaterways leisure tourism Mumbai - Wrong package given i want refund

Cordelia Cruise is a scam, i having a horrible experience with them regarding my cruise package.
I booked a package with them(Ms.Neha Singh representative) on **th june **** by paying Rs.**,*** which was **% of the total amount.
The package i booked was Mumbai-At Sea-Goa and sailing date was from **th oct **** to **th oct ****. They said i have to pay the outstanding of Rs.**,*** in the month of august in order to confirm the booking otherwise it will be cancelled. They gave me a booking number which i tried to add in cordelia app however it shown error "this is an admin booking, please contact the person who created this booking"
From **th aug **** they started sending me text messages reminding me about paying the outstanding amount by clicking on the given link, i tried that numeral times however that link was taking me to cordelia app and asking me to add booking, when i did that it shown me that same error message i mentioned above. Then i contacted Ms.Neha Singh again on **th august **** which was the last date of the payment as per cordelia's policy. She did not answer my calls so i sent her whats app message telling her about the issue and she replied me to send an email to cordelia's support team on the given email address. I did the same and they sent me a link to make the payment, i made the balance payment of Rs.**,*** on **th august **** and was informed that i will receive the confirmation with invoice and voucher on monday i.e **th august ****. On **th august i checked my email and found an invoice and a voucher containing wrong package and other wrong info.
The voucher they sent me has the sailing date from **th sep **** to **th sep **** and its mumbai- at sea- kochi which is unbelievable. I have sent them numeral emails and contacted Ms. Neha Singh numeral times but she is giving me lame excuses that these dates will cover my marriage anniversary as i told her my marriage anniversary is on sep **th and also they do not have any room available in **th oct cruise. I have already booked flights from delhi to mumbai (one way) and goa to delhi(return) and they are saying that i have to adjust in sep **th cruise.
What i want is give me an upgraded room as commited in **th oct cruise if can't then get my flights booked from delhi to mumbai(one way) and kochi to delhi(return) for * of us if can't then give me a full refund of Rs. **,*** plus compensation for wasting my precious time and ruining my vacation.
