Incompetence of Sani car rental unauthorized debit and then I am told wait 48 hours you gave Ruined our family holiday

To write a review one unfortunately has to give a star rating. If I could give a minus star rating it will even be too good. I collected my vehicle from the Lanseria branch on Sunday morning. It took more than 30mins to do the rental even though it was nit my first time renting from them and the booking was made on their website. I requested that the collection time be corrected on my agreement which was not adhere to. The actual incompetence came when they took a holding deposit twice once while I was there and although the card machine said approved remove your card Zanele said there was a time out error. After phoning the bank and waiting even longer the bank said that the transaction cleared. As many if us use 1 credit card when going on holiday I checked my banking app on Tuesday just to check all my debit orders. I scrolled to my credit card account and noticed that Sani car rental took two holding deposits and now my balance on my credit was zero and I am over my limit. I immediately emailed the customer care and was told that they will contact the bank. I use one credit card for my holiday and now there was a Zero balance and I can not buy food for my family on our holiday. I was told we apologize but wait 48hours .....wait 48hours before I can feed my family....seriously...Norman Niacker who ever he is word means nothing..Kaleb Manger from Lanseria branch....how would you feel when you have to tell your family they can't have breakfast lunch or dinner.
