Pathetic and Unprofessional service

I have sold my townhouse and it was registered 21 Nov last year. The managing agents are Compreg and their service is pathetic. I have asked for a refund of any credit due on my Levies account and emailed Judith and Monyane 17 December with a letter from attorneys notifying of the registration of property to new owner. I have now been sent an email stating that no refunds are done that I must claim this monies back from new owner . This is absurd and will never happen . I now stand to lose monies because of this . Since when do we claim back credit monies and becomes my responsibility. Pathetic service all around and outright outrageous . Why must the seller refund myself any credits due when Compeg gladly accepted all monies from myself. Compeg needs to institute this instruction
