Scammed daylight

I've been doing follow ups with this college, And they're not responding, the Lecture asked me to send my assignment so he can have a look to this day the man is not responding, I send emails to them the CC him and still doesn't respond. I feel like I've donated my money to them, I feel scammed really. Before I paid for the course they gave me so much attention, reminding me about the payment and so forth after I paid the service was terrible
