40 minutes phonecall & still no good!

I contacted your helpdesk today regarding the obligatory link between the credit card owner and the main driver.
Once a year I invite my son for a short trip and this on my account. However, he loves to drive and he drives well so I fill in his name as main driver. This is not possible, I have to be the main driver and he can be added as secondary driver up;on receipt of the car at extra cost of £10.- a day.
Your helpdesk clerk offered to cancel my present reservation and make a new one.
The first try: my contact made a new booking, but one of his colleagues cancelled both the old and the new one.
The second try: I did not have time to check all the details, but found out later that my gender was entered wrongly. I am a woman and not a man! I tried to change it myself, but no, the booking had to be cancelled and a new booking had to be made!
Sofar I received 3 booking confirmations:
346495925
392950486
379731118
The 4th confirmation hopefully awaits me in my mailbox.
This also means that my creditcard was charged FOUR times for this amount of the rental and according to your employee restitution takes about 7 days.
Apart from that I spent about 40 minutes on the phone from Belgium to England at my cost!
You will understand I am not happy with this situation and my request to you is to offer me compensation for this.
