Complaint Review: Green Tech Imaging

I received a cold call from Shawn at Green Tech Imaging asking what kind of printers I had. I told him and he asked if I wanted to try 3 toners for free. I agreed. I received the toners and then a week later I received a call from Shawn asking how I liked the toners.
It was only a week and I haven't had a chance to try them yet. The next line was that the other 9 will be coming and then the invoices. OK, I will be able to use them.
Then about a month later, Shawn called back and said another dozen will be coming. I didn't order any more but he said we sell them in lots and said we had a verbal agreement. I said that was odd but thought, well I have 5 of the same printer, they will get used. 
Then about a month and a half later I received another call from Shawn and that I will be getting the rest of the toners. I argued with him and ask what toners. Oh, we sell them in lots of 4 dozen at a time. I said I don't need 4 dozen of the same toners. He said that I agreed to buy them.
So I asked if they had toners for a color printer that get used quite a bit and they did so I said to send those toners instead of the others and he agreed. 
It is 4 months later and I purchased the 4 dozen he said I agreed to. Well, I just received another call from Shawn that 12 more toners are coming. that makes 5 dozen. These are going to be returned. I have had enough. I will use the other toners but I will not be taken advantage of like this.
I did some investigating and found quite a few negative reports about this company which convinced that this company is a rip off artist, which prompted me to file my own report.
Never again, and if anybody gets a call from Green tech Imaging, hang up right away!
This is not a very good way of doing business.
I will never take a sales call again. They ruined it for everybody else.
