scummers i did not request any information from this number so am not sure how they got my information

Got a message from someone called jemma claiming to be from alffie didn and reverse lookup says it's a construction company ' answer the call as I had already had one of those hangup calls shortly before claiming to be from my job provider. Its cant sms a reply How do they get so much info?

Heads up. I received a phishing email with this number as the contact.
