I just got the call from this number they tell all my deatails they say i won

Received 8 calls from these people in the last 2 days

Depends on exactly what you mean by "they confirmed".           Did they tell you the details which YOU told them were correct or did they ASK you the details which THEY then said were correct?        If they told you the details then they already knew them and it should be OK.         If you provided them with the details during the phone then you might well have a problem and need to take steps to protect yourself against identity theft.

Received a call from this number yesterday informing me that I had won holiday vouchers from a company called SA Netlink. They verified my postal address which was incorrect and later sent an sms from a (07) 2251 8029 saying "dear client, your holiday vouchers will be sent after your debit. Contact us on (03) 1837 0347 or info @ sanetlink.co.za" I am not interested in the vouchers

Ignored this number  6 times today. after reading this, I'm glad i did. It seems they desperately want to steal my money.
