Smart Start review: Suspended license due to failed calibration I did not know about

So my son has a smart start ignition interlock. He has had it for approximately six months. It triggered in March for a violation, however smart. Start wouldn’t tell him what it was. He couldn’t figure out why it did this and neither could be person. He took it into to have checked and recalibrated, other than him starting his car and going into the house in mornings and evenings when he has to go to work because it’s super cold and he’s warming up the engine and he must’ve walked away. However, know if there’s a camera on the device so they can easily check this to see what’s really going on.. He was told at that time the next calibration would be pushed out due to a calibration occurring early in March. Initially in March, Smart start noticed him via the device with a lockout notice if he didn’t get the vehicle in for the violation, which he had to pay for in addition to installation and monthly fee. On May 29, he was noticed that he had a calibration due on June 3. He immediately made the arrangement to have this done. On June 1, he opens up mail from the MVD indicating he failed a calibration and his license is suspended as of May 22. On June 1, Upon calling smart start they told they told him they didn’t have to give him any documents of proof and they could not tell him anything or why he was not noticed of any other calibration due except June 3. They then advised him he missed a calibration in April. He advised them that he had no other notification of an upcoming calibration except for June 3. At which time Smart Starr told him he should’ve been locked out back in April which he was not. So my question is, is there any recourse? He has lost really good jobs in the last few years over this entire case. The Courts erroneously submitted charges that were false and had to be retracted though they suspended his license and even though they should not have he still had to pay all fees to get his license back. He was told just do that because that’s the fastest way he could get it back if he waited for the courts they could get messed up again. Unbelievable! Then the MVD didn’t receive some electronic class he took which he did take and we had to get that rectified, now Smart says he missed a calibration, when in fact, he was never noticed of the calibration. So again, my question is, is there any recourse? He did request the hearing late last night to be held so we’re waiting to hear on that and he gathered all his evidence so that he can be ready for the hearing. But he can’t go without a license. He works full-time and I can’t get him there because I work full-time plus he goes to school so everything is a mess right now because of this missed calibration that Smart Starr never notified him about .
