Pathetic service no deposit after 4 months

Most pathetic customer services. After renting a property from them for 2 years and never a late payment vacated their premises 01.05.2020 took them for months to tell me that I will not get my deposit back. The unit was not damaged at all and very well taken care of there were 4 holes drilled in the lounge wall and now they telling me that the unit needed to repainted. Apparently this costed R6800 which is the exact amount that supposed to be paid to me. The invoice sent that I requested from maintenance just started painting R6800. This company is pathetic and I do not wish this upon anyone.
