My pli details are

Premium - rs 455/-

I am trying to submit my premium from april, 16 but could not deposit it due to failure at your side.
I have visited vibhuti khand gomti nagar office for depositing my premium but person told me that first i have to update this policy then i can submit my premium. I went to hazarat ganj main post office and update my policy. Your officer told me that i can submit premium online also. Then i created online account but could not see my account details online get message that contact post office for depositing premium. I again visited hazrat ganj office and your person again updated my policy but when i check it online result was same. Then i visited post office vibhuti khand 3 times and your officer told me that server was not running.
Now please told me how can i deposit my premium and surrender my policy.
