There have been serious issues with my credit card account since a double transaction message i got. Following are the sms messages i received on my registered mobile number from the bank.

7th january 2019 - monthly bill payment - i paid the full amount as per the last month bill.

Now my account balance is shown a value of rs.-14282.00.
Please explain this. I tried to make an online payment but it got rejected followed by a telephone call telling that the transaction failed because of insufficient balance. I have settled the last month bill on time and have not utilized my 75, 000 rs monthly credit in my card. Still, my balance is shown as a negative value. Expecting a prompt response from your side. I need a detailed bill for all the transaction made from my credit card from 1st of january till date. I suspect some online fraud as the numbers don't add up considering all possibilities like - the transaction of 24500 was made twice wrongly or my last moth bill payment was not successful. So kindly send details of all transactions made on my card since january 1st, 2019 and explain the reason for a negative balance.
