Hello and welcome. My name is ***** ***** it will be my pleasure to assist you.
This is a complete scam. Lottery winners are not chosen from the population at random, or from a database of mobile numbers with permission granted from the government. That is actually preposterous. This is a phishing scam to get you to reveal personal information that will later be used to commit identity theft. They will also likely ask you for money to get your prize and then disappear once you pay it.
In the next days or weeks, be on the look out for similar "too good to be true" loan solicitations, "sweepstakes" winnings, and similar windfall type offers. These will be further scams perpetrated by the same individual contacting you now under a different guise. Scammers love to double back on potential victims like this with "followup scams" in the hope that, though they couldn't trick you the first time, they will trick you the next.
In the mean time, you would be wise to immediately cease further contact with this scammer and report the matter to Scamwatch here.
If I can clarify anything at all for you, please do not hesitate to ask. It is my pleasure to assist you further if necessary....
I just wanted to followup with you to make sure that you did not have any further questions or concerns. For some unknown reason, the experts are not always getting replies or ratings (which is how we get paid for our work) that the customer thinks have gone through. In your case I have not yet received either. If you are having technical difficulties with reading, replying or rating, please let me know so that I can inform the site administrator.
In any event, it was a pleasure assisting you and I would be glad to attempt to assist you further on this issue, or a new legal issue, if needed.
Very best wishes.
