Thanks marycatherine, As per my knowledge, I have no such agreement with them. When I went to them to enquire about it, first they said "we have already informed in the last statement mailed to you". Then I took an showed the statements for the last six months, all of them from customer service staff to the branch manager showed their helplessness saying, "even we did not know, the higher authorities sent us instructions with immediate effect and we could not inform the customers" and the branch managers answer was "we will be discussing the matter in our next meeting and we will let you know". But nothing happened. I tried to make many other enquiries also, but no use.
When I understood all I am doing is nothing else than WASTE OF TIME, I had to keep quiet.
