Poor service zero response to mail communication

I have a third party claim pending with this company claim no GRP021310CLM. I was allocated to a Charlene Barnard who is a claims negotiator for Hollard. I was advised of a thirty day period in which this claim would be handled. I have sent several mails to Charlene requesting feedback but receive no response at all. I am not directly insured by Hollard but this should not give Charlene the right to blatantly ignore my mails regarding my third party claim. Perhaps they would treat the policy holders different however I will never know because i will never become one after my experience dealing with this claim. Hollard your employees are impacting on your image. The average star rating on Hello Peter tells me Im not the the only one having poor service from this insurance company.
