Bad customer service

I submitted a claim to Europ Assist in May 2017 for a doctor's visit in Australia. I received an email stating that the claim had been submitted. After that no contact no feedback. I contacted Europ Assist and there have been approximately 30 emails sent backwards and forwards. The original person I was dealing with left (Gerald Govender). I then had to resubmit all papers etc to another claims person (Pamela). I then dealt with Cyril once again submitting claim information. It is now August I still have not received any information with regard to this claim. I have also made telephone call after telephone call to Europ Assistance. No response. A claim that had a turnaround time of 21 days is still not settled after 3 months.
