Stadio Finance Department not allocating payments

Stadio is really disorganised. They sent me a statement for fees and when i contacted them to inquire why my payments are not appearing on my statement, they told me i used an incorrect reference number. When i sent them proof i used the correct reference number, they said the matter is escalated. I contacted them and they said my payment is appearing at the Centurian campus and not the Krugersdorp campus. They told me they will sort it out, but nothing up until now and i made the payment on the 6th September already, its already the 29th September.
