You should quantify this with 'in my experance', I know people who have had problems who belive that it was to blame. I stoped using it because of there warnings. Now I can't say they are true or not, but I belive it, your opnion, Alois or Saliferts Lawers are unlikley to change my mind.
I used to just buy directly from Alois and cut the store out completly, didn't have any problems with contracts etc then. Still i wish I could still buy from Alois directly, and if I was prepared to sit back and not speak my mind I am sure I could, but its not in my nature.
Your right about face to face, however I feel I am being pushed, so I am pushing back. Perhaps that shows imaturity on my part, but I see no other course of action open to me.
