Disgusting Service!

I hired a car and then through an unfortunate experience, lost the keys and my phone while my wallet was locked in the car. I was in a public place and I had to borrow phones from strangers to make calls to Europcar to request help. They told me they'd send me a locksmith and also a towtruck because they don't keep spare keys at the relevant branch. (what nonsense is this?) A towtruck pitched... and the driver waited for the locksmith for 2 hours while complaining about the job and then leaving. In total, I waited 4,5 hours before I got the help I needed, after an already traumatic experience. The service, whenever I had the displeasure of speaking to Europcar, was so bad that I gave up and just sat on the roadside with kids with me... waiting. When I did speak to the branch manager, days later, I was told that no other funds would be taken off my card and that the only cost I would incur was replacement of the key. They would only charge it to me once I received a quotation. I did not receive anything to date. However, they've deducted more money from me. I call and don't get joy. I email and get no response. Europcar King Shaka have pathetic service and I will make a point to let everyone and anyone know why they shouldn't use them, even if it means going to the media.
