State Bank Of India [SBI] — wrong amount charged

Address: Mumbai City, Maharashtra, 400078

Dear team,
I have sbi credit card in the year 2005 and it was regularly used by me and the bill was paid by me on time. However in the year 2005 sbi credit card department charged me irctc ticket booking charges, which was not done. I have raised the issue with sbi customer care & also i have written mail to sbi customer mail box, but no response. Also i have received the mail confirmation from irctc, that there is no ticketing booking from your id and no amount has been debited.in spite of providing all the supporting emails from irctc, sbi bank has not responded to my single mail. They are sending the outstanding statement since 2005 to till date, but no resolution. This has impacted my cibil record and i have to faced many challenges. Request you to please help me to resolve the above isssue
