Feedback from Luanda on insurance claim and bad customer service from Miraka

I was in a car accident 5 months ago with one of iwise clients and I've been liasing with iwise and their client about the repairs of my damaged vehicle and I've been given the run around, the cleint has reassured me that they are processing my claim and that I should speak to iwise. I've called their call centre numerous times,never get feed back and am always referred to someone else. I've now been transfered to Lyanda whom I spoke to last week who promised to call back after speaking to his manager but did not call. I called iwise again today and spoke to Miraka who was very hasty to get off the phone, did not listen to my query,impatient and rude and then hung the phone. I'm a unhappy customer as I do not believe this is the treatment one should receive from any company
