Kesari Tours — Unethical behaviour

Address:

Mumbai City, Maharashtra, 400059

We have been travling with Kesari tours pvt ltd since 2000 onwards and have done a number of tours and also recommended them to many
we have booked an tour to south America which is set for departure on 23 feb 2017 in sept 2016 at the time of booking we inquired about a room partner as I wanted the tour on twin sharing, at the time of booking they assured me of a partner, they even shared the contact details of a guest from Gujarat and all was finalised .
now in mid January 2017 after submitting all the documents everything we get an call from Kesari saying that since the partner that Kesari gave me has backed out now they then put me on triple sharing .
I made the full payment on the assurance of triple sharing. now after all the formalities been done and full payment been made just 2 weeks prior to departure . I get an call saying that I will have to pay as single occupancy .
then on what grounds did you'll make the booking and assure me, now just prior to departure they are turning back on their words.
all the receipt and booking were done on a sharing bases
this is unethical and is not the first time that Kesari has been cheating, even in the past we have faced similar incidents where their representatives Deepali from Mumbai office forgot to attach our old passport due to which we got an reply from the consulate saying our visa rejected as we have not traveled before were as we already had a UK, Swiss, Europe, Africa, Kenya, Egypt, UAE, along with many south asian countries visa stamped
on attaching our old passport on the same documents we got the visa but lost 88, 000 rupees due to Kesari mistake
this is unacceptable and is repetitive on the side of the tour company
