I just called too after the same amount of time and it was rejected even though everything is correct. I resubmitted again with a different email and address but not very hopeful. I'm just going to stick with Castrol products/rebates in the future since they always work for me. This is twice...
I had no trouble getting the Castrol rebates through this company many times, but if this one doesn't come through it will be second time I've been burned by Mobil rebates and I honestly won't buy their products again. I followed everything perfectly and received no confirmation email or status...
I work at a dealer, and they sell just fine in my area. XL and STX trims are available for $40-50k and nicer than a high option truck from 10+ years ago. Nobody is forcing people to buy Platinum trims, but they sell well too.
