Today, I got a call in the name of olivia from singtel. (65-66768201) she told me there is a problem in your singtel internet connection and some people are trying to hack your system . i will help you to clear this problem. she told me to use run command and type"netstat" .after that i gave phone to my husband and he mentioned its scam call since ours is not singtel and they are not giving return call back number.

beware of  phone number +6566768201
