Syndicate Bank — card blocked

Address:

New Delhi, Delhi

I have been trying to inform SYNDICATE people that my card has been blocked as, when i try to login my registered card on syndicate bank website it says- Due to the number of failed attempts we are unable to register your card at the moment. Please call Syndicate Bank to continue your registration. Also whenever i am trying to shop online, at the time of payment i am getting an error saying that, For security reasons your purchase has been prevented from being processed. I tried explaining them this thing and they are not cooperating, The SYNDICATE executives just say 1 thing every time "NO ERROR IS SHOWN ON OUR SYSTEM, TRY AGAIN AFTER SOMETIME" I tried many times but still I am getting this error because this card can only be blocked by SYNDICATE Bank itself..Only they have the authority and access to unblock it.It has been 1 months and still my card is blocked..They have not tried from their end to unblock it. pls help...
