 Re: Phone survey ( scam?)
The scammers will call back a few days later. Stating that since you helped in the phone survey, you qualified for a lucky draw and won some money.
Then they will invite you to go Msia (a few cases already), then say you can go collect the money there. Else they will ask you for your details and bank details. 
All posts made are of subjective nature by default, unless explicitly mentioned. I am afterall still human.
