Cell phone scam

Beware a cell scam to MTN something like this… you receive an sms you have won R98 000. You phone the no to claim and you hear you have won a holiday, R20 000 only is in cash .. they ask 4 bank & and personal details to transfer the money & R180 airtime vouchers (as admin fee). .. you sms the pin no to them… so they scam lots of people to get free airtime!! You get noooo holiday, no money…
