Refund complaint

I made an error payment of R250.00 to Wits University plus in error on the 08/12/2015. I have logged several emails and telephonic complaints and requested assistance for a refund, as I am not a student, supplier or client. This was a pure error. It has been almost 2 months of useless assistance from BERNIE GREEN - Finance-Officer. Then Melissa Saal said an electronic form must be completed, which I have done! Another useless one, as she doesn't comeback with feedback on the link forms!! I have reached the panicle of \gut-vol"and am now logging a complaint against Wits University plus finance team. They are unprofessional"
