No call back on my inquiry

I have sent numerous inquiries in regards to a part time course i would like to study, no one has got back to me, i even called in on many occasions and the person transferred me through to the part time department but there was no answer and got transferred back to the switchboard and left a message for someone to call me up until now still no call back since last year November 2015. I find this utterly disgusting and it actually puts off from studying at this college in the future.
