UBER: Ripping the clients off

My son call Uber to collect him on the 1 Jan 2016 to bring him home and i got charged R 1,500 on my credit card.<br> i contacted Uber via email as they don't want to give a contact number for what ever reason. i ask Uber to check the trip log which Uber should have which they turned around and said to me that they have no records of the trip im talking about. i say that if this is the case that Uber has wrongfully debited my account and that i would like it paid back into my account. i received an email back from Uber stating this matter is now closed because i cannot give them a record when i used Uber on this trip. the problem is money has been taken off my account and they are going to do nothing about it. i have the proof on my bank statement that shows that Uber deduced money off my account.<br> <br> i want Uber to pay back the money that was taken off my account.
