Have I been banned from purchasing PROFIS on a monthly basis ?

In order to support our invoicing on projects I need to turn PROFIS on and off on a monthly basis. The last time I tried, using a company P.O. it was a real difficult, but I finally got it started. When I was through I notified you of our termination date (as requested in the acknowledged sales contract terms and conditions) which was ignored by your staff. We were billed perpetually, and I had to contact my bank and start proceeding to stop payments, and issue a demand letter for a full refund back to the original termination date of notification rather than a pro-rated refund to the date I became aware of the invoicing fraud. Now when I am attempting to to turn PROFIS back on for another project task it won't go into my "cart".
