Review on High Yield HP 201X CF400XD Toner Cartridges - Black for HP Color LaserJet Pro M252dw, M277 Series by Tara Farmer

I have purchased this product 5 times. The first 4 times everything was fine, I ordered and received 2 packs. This time, however, it was not so. I ordered 2 packs as usual and paid $190.34 for 2 packs as before but this time I only received one cartridge. The packaging says it's for 2 packs and my invoice says it's for 2 packs, just like the product description. There is only one cartridge.
