Thomas Cook India — false promise from sales person

I got in touch with a online sales person of thomas cook asked for asian damaka tour package he sent a me a quote in email and after that was asking me to make the payment with taday for the discount and hence i accepted the quote and made the payment immediately, after i made the payment after a day a they called and said that quote was sent by mistake and asked me to pay a huge amount extra, and refuse to refund the amount also.

And after that anna nagar chennai branch gave me a quote, i got several assurance from the sales person that they also should not raise the quote after i pay the amount, the agreed upon. Even the gendral manager assured in the phone that if you want i will send an email that the quote will not raise., hence i asked quailty team to transfer the file from online team to anna nagar branch the movement that is transferred, they also raised their quote by saying airline rates have increased 4, 600 per person that too in 2 days. The the previous movement before transfering they said differnt story, the movement is got transfered every story was different.
