Immoral business transaction

I booked a car through JetCarHire (brokers in Spain, i had no idea!!!) who have Green Motion, Kenings as their service providers in South Africa. I was unaware of this, as one normally scrolls, sees a deal, and books a vehicle. The timeline: I booked the vehicle at 8.30AM on 22 September from Cape Town International to King Shaka Airport Durban for the period 22 September to 6 October. On arrival at Cape Town International Airport at 2.30 pm, I realized I had mistakenly typed in OR TAMBO instead of King Shaka as the pickup and drop off point. I immediately set about trying to contact JetCarHire and Green Motion Kenings to rectify my human error. The nightmare began. I was dealing with automated responses stating that I could not amend my pickup, drop off point!!!! These attempts went on until we boarded our plane at 5.30 pm. I tried contacting Green Motion Kenings whose phone pick up time takes at least 8 minutes. They stated that they could not help me. I informed Green Motion i obviously could not pick the car up at OR TAMBO. I even got an Investec banker to call JetCarHire. No one would help us, the terms and conditions prevented fixing a typo!!!!!\nOut of despair, I used the same companies. I booked a car via JetCarHire and Green Motion Kenings at 5.30 pm in order to collect the car at King Shaka Airport Durban. I had to pay again. On arrival at King Shaka Airport, I received a call from OR TAMBO from a Green Motion agent, stating he had my car for me, despite me informing them that I was flying to King Shaka Airport. I received the other car at King Shaka for my second paid booking.\nI have been communicating with both companies since 22 September and all I receive are automated responses from JetCarHire stating that they can't refund my first booking albeit no car was collected by myself.\nThey just repeat that t and c's were that no change could be made. It was a human error that I tried to rectify on the day and I even used their services again on the same day, parting with my hard earned pension twice.\n\nMore importantly, I have been asking Green Motion Kenings to assist because they are based in South Africa. No one is prepared to help a 68 year old pensioner who made a typo in a drop down box. It wasn't an intentional attempt to change the reservation, after all it was the same day and the same companies were utilized. One service was rendered by JetCarHire Green Motion Kenings but they were paid twice and are refusing to even entertain a plea.\n\nSincerely\nDean Sudding
