Royal Sundaram General Insurance — health policy

Address:

K-7.3,Plot no-6,Second Floor, Sector-83,Gurugram, Gurgaon, Haryana, 122004

I am holding a health policy of royal sundaram policy no. Hce[protected] and i took this policy in oct, 2016 via city bank card and then also i was holding icici lombard policy and had opted for this policy after the employees of royal sundaram assured me that my past benefit will be preserved but when i paid and got the policy documents i noted that you had treated me fresh health policy holder with a locking period of four years. Further i was informed that my premium is about rs 25, 000/- for family consisting of me, my wife and my son. I didn't raise any object to making me fresh policy holder at that time.
I was informed that premium in policy will be same for five years and will increase about 10% of the amount after 5 years and accordingly i purchased your policy. First renewal in 2017 your firm charged me same amount but in 2018 you increased the premium to 120% i. E rs 30, 826/- and on my enquiry it was informed last year that the increment is on behalf of gst and no further increase will be there for next three years.
But to my surprise when i tried to renew my policy this time i found the premium is rs 48, 547/- an increase of about 157% from the premium of last year and about 190% from the first premium paid in 2016.
I contacted the gurugram office of royal sundaram on monday i. E on 04.11.19 to know how & why my premium has been doubled and they told me to contact customer care [protected] and they will be able to help me accordingly i contacted the customer care on monday and talked for about 12 minutes. Customercare was not able to give details and told me that i will get a call from head office and on monday evening i got a call from +[protected] even before i could pickup it was disconnected. Than i called many times to this no. But mostly it failed and one time it was disconnected.
I got sms stating that your office tried to contact me and i didn't pick the phone, hence to contact customercare. Next day on 05.11.19 i again started the same process and called customercare and requested them to give me some no. Of person whom i can contact or otherwise told him to request your head office to call me from such no. Even if i miss their call, i can call them back. Again in the evening i got a call from same no. And before i could respond it was disconnected. Even your person was supplied with alternate no. Again i got same message and instead of wasting my time and energy i am sending you this mail along with the screen shot of sms and call details.
I am trying to contact you again and again but your system is designed such that customer cannot contact you and is only on the mercy of the royal sundaram. Now i am requesting you to inform me why my premium has been increased to about 200% in three years even when i do not have any claim after taking the policy and i have not requested to add anything extra in my existing policy.
Hope for immediate response.
