Appalling service

I lodged a third party claim with Frontline insurance after one of their clients drove into my car whilst texting on her phone. Nearly 7 weeks later the claim has still not been finalised by Old Mutual (I’m assuming they are the underwriters for Frontline ????♀️) The first consultant apparently left Old Mutual without handing over the claim to anyone. The second consultant was moved to another department, and the third consultant, who has had the claim for 2 weeks, has not even bothered to contact me, not even once. Their service is beyond pathetic!!
