Received text for secret shopper opportunity, returned a yes to the text. ®received notice that I was accepted and that I would receive via USPS instructions. Today received a a priority mail 3-day envelope with a cashiers check for $2180.10 with instructions of how to cash it and place it my account. I am to keep $200 and spend the balance at a Walmart store that they would tell me which one after I call them to say I’ve received the check. After the deposit I was to call them and inform them that it was deposited and then after two days I was to again call and tell them it was in my account.The bank that the check was from does not exist (First Tech, Beaverton, DR 97075-2100). It states that the "original document has a true watermark" this check has no watermark.I have not and will not cash the check nor will I call the 707 number.The original message had another telephone number 833-228-0837.
