Infinity Printing Supplies (IPS) Ink Cartridges are defective Granada Hills California

We received some ink cartridges from Infinity Printing Supplies. At first the cartridges worked in our printer just fine. After the first round of cartridges Infinity sent us were empty, we used the other shipment that they sent us. Each cartridge that we put in our printer now says that it is damaged and we can't use them. I am currently trying to send all of the cartridges back and get a refund. They are also very secretive on the phone when they call. If the person whose name is on the account is not available they will not leave a message or tell my staff the name of their company so I can call them back. Looking back on it now that should have been a RED FLAG. Be cautious when dealing with this company and do not accept anything free from them in the beginning.
