HDFC Bank — debited money from my insurance policy and auto debit activated and debited money for my both policies - policy no. 20389379 & 20389381

Good evening

I was gone weekly unit statement for policy no. 20389379 & 20389381. I have query regarding the deduction amount in the statement as follows
1. Due to this current pandemic i can't able to continue to pay the yearly premium, as mentioned by the advisor changed to monthly mode. I saw deduction of 295 inr.
2. I can't able to pay the premium on time, so for that policy lapsed charges was deducted again 295 inr.
3. I paid the premium as one time on[protected] payment of 8334. I can see in the statement it was deposit only 4167 on[protected] and 4167 on[protected] i. E after 8 days.
Can you explain me the above query's, as i am already struggling to pay the premium every month as i lost my job, still i am managing to continue my both policy. Need your kind attention
The below is my premium paid chart from june, july, aug month. I am paying manually every month. Suddenly auto debit was activated and you debited money from my account.
There is no communication from hdfc life that my auto debit is activated and it will hot your account on so and so date.
Suddenly you debited the money can you please return my money and cancel my auto debit.

I need explanation from hdfc life why auto debit premium was debited without my knowledge and suppose to send me mail 15 days prior of the emi date. And i am not aware of the auto debit date also.
