Incompetence and unrealistic

M very angry and disappointed with Tempest, we hired a car on the 23rd of December and returned it on the 29th of December 2019, today when I was doing a follow up on the deposit of R2000 that was still with them they told me that my refund is R38 and i asked how is it possible the lady said she will send an invoice. Till now m still waiting. Tempest OR Tambo.
