Europcar doesn't respond to my email!!

On Saturday morning 28/11/2015 I got into my hire car (Kia Rio) in Cape Town. I needed<br> to drive somewhere after just dropping my husband and 2 year-old son<br> at the house. As I got into the driver's seat, I realised I had<br> forgotten to give him the baby bag, so<br> picked up the bag, got out of the car (leaving the car keys inside the<br> car - not in the ignition), closed the driver's door, took the bag<br> into the house, and a minute later was back at the car ready to leave.<br> To my horror I realised that the car had locked itself automatically!<br> <br> I was in a big rush as I had to go and fetch the bride who was getting<br> married that day, so I was extremely upset that your hire car would do<br> something like this. None of our cars we use at home behave in this<br> way.<br> <br> I contacted Europcar, who said the car keys were in Johannesburg. Your<br> agent arranged a locksmith to come out and open it. He came within 20<br> minutes, and required R550 cash on the spot, which of course I had to<br> pay.<br> <br> Due to the illogical nature of the Kia locking itself, I feel it appropriate that these costs<br> should be for the account of Europcar. Kindly arrange a refund.<br> <br> Please get back to me regarding this ASAP!! It's been over a month!
