Galaxy Watch 6 Classic Activation Issues

I recently received my new Galaxy watch 6 classic and each time I try to activate the device after entering the IMEID it says the device is not compatible. However according to this article this watch is listed as one of the supported devices. I have chatted and called numerous times, and everyone just tries to sell me the same watch I already bought. I am not sure what to do here?
