Poor customer service

I hired a car and picked it up Wednesday 23rd of December. On the 24th the car just did not lock, even the manual lock was not working. I called europcar and they said they will send someone to pick up the car, but nobody showed up the whole day. I called the call centre number since nobody was answering the phone, the europcar call centre said they will call me back, nobody called back and nobody came to pick up the car. I called europcar again in the morning and they said they will send someone as soon they can access the cars. I waited, nobody came and nobody called. I am stuck with car I cant use and europcar keeps on ducking and diving, now nobody is answering the phone and I have been calling all morning. if this car gets ****** they will blame me, but I have called way ahead of time reporting this issue. EUROPCAR CUSTOMER SERVICES SUCK!!!
