City of Cape Somerset West community hall took my refund for themselves

I got married in Somerset West hall on the 8th of December,a friend who was our wedding planner did most of these arrangements,every payment we would submit our receipts as proof of payment..and we were promised that the refund of R1130 will be paid back to us in three full as per turn around time and after four weeks I sent an email to the administration inquiring about the delay I made phone calls and people who were busy will our processing were acting of sick we finally got the feedback after few days and we were told that we owed R307 that's why it delayed this was shocking to hear but I gave them a go ahead to deduct it on the refund amount three week passed the new story is that the person is on leave who was busy with my refund and to my mind I got shocked.busy with the refund??? How long does it take..my contract states that the refund will be paid within 3 week I am very angry with this treatment and poor service that we are receiving and sick and tired of the lies..as little as it is it's my money and I will go further that this
