Bt Company — prize claiming

Address:	51001
Website:	Bt company

Hi sir / madam
My name is ernest from zambia, i received an sms saying my number has been granted one million great britten pounds from bt company random draw. I was asked to provide my number, my details and my email address which i did they sent me approved forms which i filled in then sent back they sent me a certificate from prize claiming and i sent to the lloyd's bank where they said it was being kept. After some time i want to contact them the email was blocked. So i want to if this draw is fake or real.
Thank you
