Accenture India — Accenture is not answering and not refunding my money

I have opted for Group Medical Insurance Policy in year 2021 of amount Rs. 38, 340. But Accenture had deducted my money twice(1st time - Rs. 2, 244 and 2nd time - Rs. 38, 430).

I have raised about this issue multiple times while I was Accenture's employee but still it was left unresolved. Following are the tickets which were raised -

PR2247474
PR2259010
PR2325499
PR2325532

The 1st ticket which was raised PR1991043 was resolved by mentioning that the amount would be adjusted in the new year policy. But the issue is that I have switched my company and not continuing with my plan and this had been informed to the concerned multiple times.

After leaving the company also I have been following up on this with Accenture but I am not getting any response on this issue. Kindly refund my extra money which was deducted.
