help with back on track program ontario

so my bf got a roadside suspension for blowing 0.1 over, and its been probably about 3-4 weeks now. we had to wait a week for the suspension to be lifted and he got a temporary license in the mail. we paid for the 8 hour back on track course, got the email with the list of providers to call based on the region you live in. weve waited in queues for hours multiple days in a row and keep getting transferred to different numbers, and finally i think the number we are supposed to call to actually book the interview/course date is the mississauga/peel region is 905) 629-1007, ext. 2225. weve called them MULTIPLE times and left voice mails, and we havent been getting a call back. its extremely frustrating because the process has been so complicated for NO reason, all because he blew over 0.1. obviously hes gonna be more careful about driving in the future but the hassle this has been when he wasnt even driving in a dangerous way, he just got pulled over because of something about his car. i dont know how its taken so long for us to get a call back so he can do his interview and book his course date, he calls multiple times a day and the phone line is always busy and goes straight to voicemail. he just wants his license back already
