Indusind Bank — deducted rs 999/- from indusind bank credit card without my concern

Dear sir,
Rs. 999/- deducted from my indusind bank amazon pay credit card no. [protected] for amazon standing instru. I didn't take any services. Its debited automatically which is not done by me and without my consent.
Please look into this matter and credit rs. 999 /- in my indusind bank amazon pay credit card dated 20th april 2020. I am shocked because i believe in indusind bank credit card. This is first time i face this type of problem. I tried to contact customer care but customer care services is currently not available due to cronavirus at this time.

Please look in to this matter seriously and resolve it asap
Regards,
