Watch out

Was contacted via SMS to say I won R2 million. Was asked to email them back with the reference number provided. I did so just to see if it was legit. I was then emailed back by a Dorothy van Der spys saying she is the payout manager. They wanted my name, address, tel number and banking details to pay this amount out. The thing that triggered me to believe that it's a **** was the wrong wording used. Could be or couldn't be a ****. I'm just very weary of such things and won't take a chance
