appalling ptc support compared to igrafx
A while back I bought a mathcad 15 license from a small uk engineering company who were moving location and disposing of filing cabinets containing lots of old software they hadn't used for years. The employee provided sufficient details of the company to uniquely identify my license. Despite this PTC Curstomer Services said they couldn't identify my license, relegating my disk to a coffee coaster.
The other day I updated my copy of Igrafx Flowcharter. A very serous piece of software and company. Unfortunately the reseller hadn't packaged it well and it arrived shattered. Within 15 minutes Igrafx had emailed me back and provided a link with a download and new key for me. What a difference between PTC and Igrafx.
