The caretaker or the municipality must pay back our money

On the 15th of September I have booked the community Hall in Extension 9 (Grahamstown) for our Grandmother's funeral. We were told to pay a refundable R450 upfront except the rental money for the of which we did. Same afternoon after the funeral I completed a claim form with the caretaker of the hall for the refund. Until today we have not received our money. Whenever I call the Hall caretaker, he promises to call me back but not even once he followed up with me regarding this money. It is very disappointing what they do to bereaving people. The money might seem or sound small but the family needs it.
