HDFC Bank — HDFC bank employs cajoled me into buying their policies but now ignore my issues regarding them

Address: Sanjauli, Shimla

The HDFC bank at Sanjauli Shimla- Himachal cajoled me into buying a lot of their policies . I pay a premium of over 15 lakhs for them every year. Until I had not bought the policies they would give me the best customer care. But not they are either incompetent or simply ignoring all my issues.
My issue is that they made me buy so many of these policies that I have not been able to track them. And when I ask my HDFC branch in Sanjauli - Shimla about it, they seem as clueless. I have been asking them to give me a list of all the policies I bought through them - and they give me only piecemeal information - not the complete list, Some of the policies they gave me they have themselves have forgotten and I have to remind them about them. It is really frustrating. They now tell me they will find out the details but never do . They say they will visit me - but never do. They they say will call but don't. What should I do ? This HDFC bank branch has a review score of 1.7 on google with all customers frustrated with them - so I wonder how will my issues get resolved?
