Caller: Last Minute dot com

I received this phone call today in the afternoon. A lady with a south Asian accent stated that she is calling from Last Minute dot com about my holiday in May. Then immediately she demanded my email address to pass security. I challenged her with more information about my alleged holiday to make sure she is from Last Minute dot com. She refused to give me any information about my proposed holiday because of data protection law. As a last resort, I asked her to send me an email message to my email address on file so I can make sure that she is from Last Minute dot com. I checked my email inbox and there wasn't anything from Last Minute dot com. It must be a scam attempt.

I called back number 020 3499 3457 rang once then gets disconnected automatically.
