Bad ****** service

I booked the car online on the 26th October 2023 for 3 days from 27th October 2023 and the money was deducted however hot a call from some lady at Williams Hunt in Centurion telling me the car i booked online which was a VW Polo TSI for R2292.30 they don't have it but they have a Polo Vivo. This is not acceptable and now refunding my money wont be immediate so am wondering where should i get the money to book another car somewhere else cause i have a funeral to attend tomorrow. Am really degusted and frustrated by the level of service from this entity, I have been holding for more than 10 minutes ***to speak to an agent.... My confirmation number 14N92X
