This company sent me a check in the amount of 3992.00 to do mystery shopping. Out of that amount 550.00 of it was mine to do the assignments. Seemed ligit. Check looked real and all. I deposited the check. A day or so later my bank tells me its a counterfit check and now all MY funds that I had before the deposit are on hold due to this counterfit check!!! Do not deposit a check from MARSHALL E CAMPBELL CORP for marketing research. Its a scam!!! I contacted the actual Marshall E Campbell company and they are a electrical equipment distrubitor. They are aware of this going on and are taking action!!
