I signed up with International Service Checker and passed their tests for becoming a mystery shopper.I was assigned a job with a computer testing service, they wouldn't post the job information in my personal box, they made me confused about what the assignment was supposed to be.
There was No organization with this company only confusion. I wrote several emails to them explaining this confusion. It took them forever to get back to me they even reassigned my job but the same thing happened, no organization, no training for the job, nothing. I was getting a bad feeling about National Service Checker and found out though research that this company promises to pay you anywhere from $10-$200 for an assignment only to pay part of what they say or sometimes they don't pay at all.
It was one big headache for me.
My advice, DON'T SIGN UP WITH THIS COMPANY.You will get BURNT.
