Appalling service

I am renting out my property in Mohlakeng from July 2020.The first tenant vacated the property on the 30th November 2020 after defaulting on her payments as well as the municipal account.I paid the municipal account and requested for the deposit of R4500.00 to be paid back to me,however I was only paid an amount of R2479.25 on the 18th February 2021 which is two and a half months later.I have been struggling to get the difference of R 2020.75 to date.I have enquired with the two ladies at the Randfontein Office without any success . Today (15/04/2021) i enquired again and have since been blue ticked on Whatsapp by one of the ladies in the Randfontein office
