Complaint Review: viewasonic corporation /white bear lakemn 55110

I am an Avon Representative and received an email from a woman who called herself,

Nikki Tyson. She ordered Avon from me. She told me that the company that she worked 

for would send me a check for payment. Today , I received a check through UPS for $2600.00

Her order was for under $500.00. In the email that she sent me today, she said that her company

accidentally sent her travelling expenses in with my payment. She wanted me to cash the check

and mail her the remainder. The company that the check had on it was ViewSonic Corporation

 White Bear Lake, MN 55110 and was signed be Ted Sanderson, The return address is Benchmark

Properties in Tallahassee, FL 32301. I emailed her back and told her that to send me her

address and I would send her the check back uncashed and in turn she should send the correct

amount of what she ordered in a cashiers check or money order. This sounds too fishy.
