BTW these calls are free at anytime of the day or night. This is a big problem with IBM cards. Most Card manufacturers get label crazy silkscreening their name and the card's name all over the card's breadboard, yet IBM being the marketing giant doesn't need the extra production step and goes with bare breadboards. Contrary to popular belief you can not tell what the card does by these numbers as a class, ie not all 87Xxxxx cards are disk controllers and made in 1987. With all the numbers written down place the card in a anti-static bag and store it carefully.
Chances are if the card is over two years old it is going to be a gamble at best.
If they could not help, it is time to post your problem to comp.sys.ibm.ps2.hardware for answers.
