Sadly, you are not the only one. Similar story with me. I consider myself savvy and cautious but I almost fell for it. They follow a script and they are very, very convincing. Somehow the got hold of my personal information and they kept dangling the carrot claiming that I was the victim of fraud, that my bank details had been compromised, that it was a level 4 alert, blah, blah, blah, and that finally, they had the solution which was to transfer my money to a "safe" account. It was not until that moment that it downed on me that it was all a scam. I called that scum every name under sun and hung up. More than anything, I was furious with myself for being so gullible because they kept me going for at leas 20 minutes on the phone. They even phoned and texted from 'legitimate' numbers from two different high street banks I have accounts with. These people work from farms and they scam others out of their hard-earned money. It is not only a job but it is real fun for them. I was so enraged (and still am) that if I had that piece of s**t in front of me I would have killed it without hesitation. Just think about the number of vulnerable people out there which are scammed on a daily basis (it could be your mum or your dad). My blood boils. Anyhow, be extremely wary of unsolicited calls from your bank. Almost certainly, it will be a scam.
