kleritec Deceptive from the first phone solicitation Sylmar California

I have been dealing with this company for the past 2 years.  First phone call told me for $199 I would be recieving a box of surplus school supplies.  Trying to save money I agreed but I kept asking the rep if this is the only shipment and payment I would be obligated for and she assured me it would.  Recieved the supply box and was happy.  Then I recieved another box a couple of months later and was told it was the back order to the first box and I don't owe anything.  To make a long story short I recieved a total of 3 shipments, paid $600 for them because a collection agent called and I just wanted to be done with this nightmare.  Just recieved another phone call today informing me that my "back order" has been shipped!  I flipped out!  Come to find out I owe another $600!  I told him I would not be paying it and that his company was deceptive from the beginning.  This has been a total nightmare and I told him that dealing with his company was like walking down a hallway that never ends.  Do NOT engage this company!  The product is good but not worth the nightmare.
