I booked 2 international flights on makemytrip.com in Sep 2012 with my SBI card, and as per an MMT and SBI offer, I was supposed to get 11% off on each flight. When I booked, I entered the voucher code given, but they told me that the discounted money will be credited to my account within 14 days of booking.
I waited, but nothing ever came. When I called their offices in Gurgaon and Chandigarh, some of their executives simply disconnected the phone without answering my questions, which is very rude, or they kept telling me nonsense likeI will get the money after I complete my journey or I did not enter the voucher code orsince departure city of one of the flights is ex India, I am not eligible for cashback orI must call SBI.
I also called their office here in Bangalore, but they simply said they cant help me.
The offers on the MMT site are very attractive but my advice is - PLEASE BE CAREFUL of them, especially with online transactions. They can try to cheat you. I dont think I am ever going to use this MMT again unless really necessary.
