First of all, the fact that they show that checks were sent out on the absolute last day possible is a sign of potential shenanigans.
Next, all of the replies that I have received from Sinclair about the issue have been copy/paste responses from their website. I asked for an answer to a simple question. I asked, "Can you confirm that the USPS actually received the envelope with my check in it on 9/30/21?" The reply was unprofessional, lacking details, and was a copy/paste job from their website. That's another bad sign.
A previous poster doubted whether Sinclair actually missed their stated 9/30 deadline. Really? I see signs that point to them missing the deadline.
It's not THAT Sinclair is late getting out payments. Its HOW and WHY they are late getting out payments, and their lack of transparancy and service. All that is needed here is a quick email explaining their situation, to update us on when we should be receiving our check, and a quick "we are truly sorry." When it comes to shopper payments, we are as much a customer of their business as are the companies that they contract with to perform evaluations. They are not providing us with proper service, at least with this payment issue.
