TSB scam,could be other banks

I only use my bank card for withdrawing money unless my credit card "won't work"
Message from TSB asking if I have made "these" transaction one was mine and the other was not.
Decided to go into the bank to sort problem out.
My card numbers had been compromised,
while in the bank a call from TSB fraud department,
I answered the call and waited thirty minutes for the call to be connected and then game up,
I presume that TSB use an automatic dialer.Just be careful.
