Makemytrip (india) Pvt. Ltd. - Ridiculously Poor Service, Non-cooperative Behaviour And Incomplete Information

My name is Prashant Omer.
I made a booking for Visa for Singapore on **th Feb **** and paid Rs. ****.
As per instructions I waited for an Agent to call from MMT to provide details for additional documents required and Courier address to send documents for the process.
Next day **th Feb **** at the edge of working day time *:** PM I received a call from an agent name Santosh Singh (Santosh.Singh@makemytrip.com) from MMT Visa Team, The Agent handling my file, who was in quite hurry at the moment and refused to listen to my word and just imposed the sentences in Unclear Voice and sent me an Email with Incomplete Information, which doesn't has the clear instruction for documents and additional documents required for Local Contact/Concent/Invitation letter formats or Account Statement related queries. Even there was no Contact number of his service desk was provided to contact him directly in case of requirement.
I sent Reply email just in * hour after I received his email to provide me details and documents format.
I am contacting customer care continuously but unable to reach to him.
But it's been more than ** Hours and I haven't received any response from him neither on Call nor on Email.
The Agent is so busy to even attain and respond in email and queries of customers for whom they have been given the responsibility.
If The Agent was in so hurry then he might have called me on *th Feb, but this kind of behavior shows How Poor Service Mmt is Providing to its Customers.
And I can't Cancel My booking at this point even it was assured on Emails just after I made booking that I can cancel booking before ** Feb ****.
Now it seems like I put my money in the wrong hole.
