*****ulent transactions

I had 30 "trips" between 11:01 pm and 5:30 am this morning in Johannesburg (I am in Cape Town), ranging from R50 to R300, costing in total roughly R4,000. I notified my bank and they cancelled the card immediately. I notified Uber, and despite providing all the information they requested, they informed me several hours later that they could not locate this charge with the information provided and asked for exactly the same information that I provided, which is in the conversation trial on their app! Either their own system of logging issues is not working or they are delaying dealing with the issue. I have seen on hellopeter other cases like this, so clearly this is an Uber problem. I will not provide them with my credit card details in future and will rather use another e-hailing company.
