Clo,
I had a similar experience a couple months ago. Mrs. micro and I returned home from a visit to our newly born grandson and received a call from Bank Security which carried my personal Credit card.
They said they noticed some suspicious purchases and wanted to go over them with me. Turns out there were two purchases that were not mine and they got on it right away. Also canceled my card an sent me a new one in two days.
I do not have any other services at this Bank and I was highly pleased. For that reason they are my principle credit card and keep a couple others as secondary.
When you find a bank that is pro active like that, you want to keep them!
Great experience for your son too!
the best,
micro...
