STILL WAITING OVER 1 MONTH LATER

I rented a car online from Budget rent a car for a trip to Cape Town on 23 January. On arrival to Cape Town International Airport, I rushed to the Budget desk in a hurry to get to a wedding that day. I had no luck as there was a very long queue and it was not moving. 45 minutes later I reached the front and a less-than-enthusiastic employee attended to me with no apology for the long wait, but simply that the system was down, or something to that extent. After a long process of the usual excessive typing, I realised that unfortunately my car license had expired and I could no longer rent a car. I was promised that the amount deducted from my account for the booking would be refunded due to the unfortunate circumstances. It is now 10 March and I am still waiting for any indication of the refund and I have emailed reservations at Budget directly for some feedback, to no avail. I am left with no intention of returning to Budget due to their absolute lack of administration skills and interest in customers.
