[Resolved]  Citibank - World Money Card — Not ready to refund my balance

Hello,
When i had to travel to my client place, i have received a WTM (World travel money card) which my company has arranged it for me from the so called CITIBANK. When i have taken the card, i have given my passport's copy along with the application filled with the necessary details.

Now after i came back and contacted citibank for the refund of the amount which was there on my card as balance, initially they told me the pin number which i have told them is wrong and said they cannot do the refund.That i have verified and confirmed that in their mailing address they have the same pin number what they told.They accepted as their mistake. And this time they came up with a new funda saying in their system it has been entered as 'Male not 'Female' and they cannot refund the money as long as thats not correct. I have given the copy of my passport and properly filled application form and it was their mistake they entered it wrongly and i had to suffer for it. I literally had to blast on those people. Still there was no way and they asked me to send a fax mentioning the problem and they will update it within 24 hrs. So I had sent a fax addressing one mr. Sreenivasan (as told by those customer care people).Next day i called and confirmed that they received the fax and they will send the cheque.
No news for the next 2 weeks. Again i called up and asked. Again they told met he same reason of 'Male' Female. Then i told them about the fax i had sent. then they were not aware about such fax and they cant find any.
Now I really dont know how do i get the money back? If i rate banks for their service, citibank will never come in the firstn 1000. The worst service i have ever experienced. My experience is not only related with this card but also with the savings account and the credit card i hold it from citibank (As i didnt have a choice to opt for another bank as they have been given to me as salary account).

Can anybody suggest some ways to get my money back? How can i escalate this to some higher authorites?

Poornima
