Terrible service

Since the end of September I have been trying to sort out a 3rd party claim with Old Mutual Insurance. I am not the client, I am the person who’s car was driven into by an Old Mutual client. I have sent countless e-mails, made numerous unanswered calls and I am no closer to having my car fixed. I can’t believe it is my responsibility to go to all this effort when I am the innocent party. In their correspondence I was told a 30 day turnaround time. I supp**** paperwork, photos, quotes you name it. And then nothing. No reply, no follow up until I HAVE TO ASK FOR THE UMPTEENTH TIME WHAT IS GOING ON. Is no-one at Old Mutual competent in handling a 3rd party claim? Would not recommend becoming a client if this is how they treat others.
