Digital BW, The Print

Have any of you good folks who use MIS inks run into Quality control 
issues? 
I have just started to use them and was getting some great results in 
with my Epson 2000P. I am using their pre filed cartridges of the 
UTFSN ink set. When they work I get a very nice neutral toned B&W 
print. They really look good. But I just got my second bad ink 
cartridge from them. The first one leaked and was unrecognizable to 
my printer. So I got in touch with there customer service dept and 
they said ship it back and we will send you a new one. Well ok but 
then I am out the cost of shipping it back. Well the six bucks would 
not break my bank so I did. In the mean time I ordered a second 
cartridge of the five shades of gray to replace my color cartridge. 
Well I put it in my printer and I am told that the cartridge is 
empty. At this point I am a very unhappy camper. 

I called a friend who refills her ink cartridges and get her to bring 
me her chip resetter. Well I reset the chip and put it back into my 
printer. It still says that it is empty. I can put my Epson ink back 
in and the printer is happy. 

And of course all this happens after MIS is closed for the day. So I 
left them a message and I hope to hear back from them first thing in 
the morning. 

So my question is have any of you had these same problems or is it 
just a run of bad luck. I bought a new hard drive on Wednesday and it 
was bad?Go figure. 

Thanks for any input you good folks might be able to give me.
