worst service

I’ve been struggling with them since last week Monday I had to call numerous times to follow up and everytime they say they will call back and everytime i have to call back to follow up. Even had a disputed with they found that it was a staff error but still am at the loosing end. Feels like I’m at fault and not the party that caused the damage. I’m without a car and no feed back on my car hire. This is very unacceptable.
