Kesari Tours — extra charge for deviation

We went to your Borivali office as we were interested in US tour. Your representative Ms. Kalpita explained above tour under bonanza offer.
Following points were discussed in meeting.
1] Deviation for journey dates will be provided by Kesari as per our requriement.
2] But tickets will be booked by Kesari for same flight only as per tour plan with different dates.
Mumbai to JFK going and IAD to Mumbai return
3] If tickets required for other destination then additional cost.
4] Tickets will be booked after visa approval.
5] If visa is rejected tour cost will be adjusted against other tour.

Since we wanted deviation both ways and our experience of Europe tour with Kesari was very good we booked above tour on 6.10.17 by making full payment.

After getting Visa deviation dates were sent to Kalpita on 21.11.17. Visa copy was sent to her 4.12.17 with request to inform flight details so that deviation dates can be confirmed. However she replied that flight details are not yet confirmed.
After continuous follow up she replied to my phone call on 3.1.18 stating that flight details have been finalized. We provided deviation dates on 5.1.18 w.r.t revised schedule to book tickets. In reply to my call she informed that now there is change in policy and you will have to pay extra charges for one deviation & one deviation is free. Then she sent mail giving deviation of Turkish airline with extra cost of Rs.8000/- per person asking me to give confirmation on same day.

Next day I went to Borivali office to see senior person. I met Ms Kshama and expressed inability to pay additional cost as it was never informed to me from date of booking 6.10.17 to 5.1.18. She gave alternate proposal of Air France with extra cost of Rs.5000/- per person and asked me to give approval immediately as price may increase.
As there is no alternative and our tour was at stake I gave approval reluctantly. Then we visited your head office at Mahim to meet Senior manager. But we could able to meet Mr. Darshan and Ms.Vishakha, nobody else was available. We explained all above facts and our grievance with request not to charge additional cost. Everybody informed that they will look into the matter. However there was no positive response.
After that I paid extra amount as I feared that there may not be co-operation from your staff if I put mail to Sr, management.

Now I have finished my US tour, hence I am sending this mail with request to repay me additional charges.
