Poor after servive at Avis

We booked a car on the 14th December 2025 and were meant to pick it up on the 29th of December from Mbombela to JHB. We then cancelled on the 22nd approximately 7 days before the collection date. Same day after cancelation we made another booking, we booked d for a Polo on that 22nd and upon collection on the 23rd there was no Polo and no similar car we were offered another car that was way out of our budget because we had not much choice we took it and paid double the amount we budget for. The painful part is. After all that we returned the car on the 01.01.2026 and up to today we haven't got our waiver back not even oir cancelled booking money.. R13330 waiver still sitting with Avis in this stressful month of back to school.

This is my worse expirience i swear. Can someone higher at Avis pls intervene and gibe us our money back and we need compensation for this poor service as we ended up borrowing money for all school expenses.
