Locker not provided

I was in need of a locker and as i have my account in Kotak , i contacted my bank for the locker. I received a call from my account manager and he assured me that if i did the 1 lac investment with them they will provide me with locker within a week. They came at my house on 31st of march and showed me the plan. I request them to give me sometime to think but they forced me to do the payment. As i was desperate need for the locker, i gave in and took the policy with them. After that it is 23.09 and they still have not provided me with a locker. I call the person that came at my house every week but he keeps giving me another date, telling me problems with the branch manager etc. These past 5-6 months have been a nightmare and my 1 lac rs has gone to waste as they are not able to provide me with the locker. As i belong to the middle class i am not sure how to afford another one lac and do the investment with any other bank. I did not expect that Kotak Mahindra will do such fraud with me and trap me like this. I do not know how to get out of this situation and get my refund and the customer service is not going ahead with policy refund as 5-6 months have passed. Really really disappointed and will never go with any Kotak service. They don’t deserve not even a star but i guess i have to give it to them. Completely pathetic service would not recommend to anyone.
