IDCSERCO SENT TONER WITHOUT ORDERING LOS ANGELES California

This company sent us a Canon box of toner out of the blue. Of course someone signed for it and we paid the bill. No one knew what machine it went to so it got put on the self. That was in March 2016. Just recently the same order arrived times 3. I called this company and complained. So, they are doing me a BIG favor by replacing these with a toner that we can use. Normally my toner is 140.00 but these wonderful people are giving me a reduced price of 349.00 per cartridge. I am at my wits end argueing with these people. I see other complaints about them. WHY ARE THEY ALLOWED TO STAY IN BUSINESS?????????
