INDIFFERENCE OR INCAPEABLE ???

I had a stand at Negester Retirement village on the outskirts of Bela Bela, which I sold. I notified Bela Bela Municipality on 20 April 2024 that the stand is not in my name anymore. I gave them the name of the new owner as well as the proving letters from the attorneys. I requested them to refund me for moneys in credit in my name. NO REACTION !!! My e-mail was sent to P. Thobela, V. Khube and RMR Masoga. I e-mailed the same officials again on 4 June 2024 with the same request. I received notification that P. Thobela has read my e-mail. NO FURTHER REACTION.!!!! I sent an e-mail to the same officials again on 17 June 2024. NO REACTION!!!! Please help.
