Caller: Vettrak

Vettrak is the student management system our Community Education Centre uses for the course I'm on. When I got messages about classes being cancelled from this number I thought someone had hacked tthe whatsapp account our class is using to keep in touch with each other. No, the classes were cancelled and Vettrak used this spoofy mobile number. Strange.
