Facing problem with Bank Muscat

I've been an good customer of Bank Muscat and made all my financial transaction from them. Recently I've received a call from Bank Muscat customer service asking for some of my details. The funny thing there was he wants to know if I have use my card in other country because they are facing problem and need to verify things. From that day onwards I am afraid to use my card and I became paranoid about my money on the bank. I am now thinking of shifting to another bank Oman Arab Bank maybe. I feel that bank muscat is not a very secure bank. I am still observing what will happen but as a precaution I withdraw most of my money from there, until I feel the bank is ok.
