Lack of professionalism

I wanted to register to study further with springfield, however they brought to my attention that I had registered before and had outstanding fees, I then wanted to know how do I go about paying my outstanding fees or if it was possible to add the fees to the current fees so I can register, the receptionist was clueless and referred me to write an email to their college. I wrote 5 emails and there hasn't been any response, I then used their whatsapp line and it's been a month of no action as the person in the whatsapp line says they can't help me and I should go to the college. How when college was the first place I started at?
