It's a scam. As others have commented, they ask to speak to you about your 'housing problem' Best advice, hang up or don't answer.

Didn't answer but must be spam. My phone reckoned it's spam. Google reckons it's BT but I don't have a landline and haven't for over 10 years. I have also never had any account with BT ever.
