Alamo Janitorial & Supply, Inc. Rip Off Las Vegas Nevada

I was contacted by this company informing me I should purchase this special long lasting ink cartrages for my business, I did agree on two black and one color cartrage,since I don't go through that much ink.  Ok I recieved it didn't try it yet, then I get a call from a sales person asking if I got the ink, I did, now today I get a call from sales person telling me I have to buy 4 more black and 5 color to complete my order, i didn't order all this ink and was not told i had to complete or order more. at twice the price I pay at another local store.from the other reviews i should neve have purchased this ink to begin with and will refuse the order they insist I need to purchase.
