Make My Trip - Horrible Experience

I am writing this to share my horrible experience with Makemytrip. This was the first time I was using their services. Back in September, after going through the holiday packages offered on their website, I was interested in booking one for Paris and Switzerland (ex Delhi dtd ** Jan ****). I got in touch with their sales expert to discuss the details. My major concerns were if payment could be done by international card and the visa process. I was advised in positive regarding payment and assured expert visa assistance. As I reside outside India, I decided to apply for my own visa and required their assistance only for my partner residing in Delhi. After finalizing the deal, I visited the online payment link and international card option was not working. I got in touch with the sales expert and was advised that the system is down. I was told to arrange payment through Indian Bank account and as early as possible as the slots were getting filled. Painstakingly I arranged the money from my Indian account and made the payment.
Soon I was contacted by their visa expert who advised to arrange the necessary documents for my partner by November to apply to the French embassy. He provided us a checklist of required documents which were more than the ones mentioned in the French consulate website. However considering he is an expert, we took his advice and arranged all of them. He double checked all the documents and my partner submitted it to the consulate. In a couple of days we got a rejection letter. Meantime the visa I applied for myself was approved. Perplexed I asked him the reason (Consulate rejection letter was vague) and the future course of action. He advised to reapply with the same documents and a better cover letter. I was shocked to hear his response and was skeptical that it will work. I did my own research and the only solution I could find was to sponsor my partner and that would increase the probability of acceptance. I was amused at how I have to advise the expert on the future course of action. Then he provided me with a list of documents required for sponsorship. He sent me a draft sponsorship letter and asked me to just fill in the name and other personal details. The draft was filled with grammatical errors and contained inadequate information. I did a bit of research and wrote the letter myself. Sadly it got rejected again. The expert advised to reapply without giving any directions of corrective action. Feeling completely dejected and not wanting to waste more money on application fees, I decided to change the booking to another destination which has visa on arrival. But the sales expert refused stating that they have already paid vendors for my booking and told only option available for me is to cancel the booking (incurring **% of the package cost).

I was really disappointed with the overall treatment. They assured me of false promises, provided me with ill advice regarding visa and were totally dismissive regarding any other solution. I have used various travel agencies in the past but never faced such unprofessionalism, incompetence and indifference.
