Disrespectful claims consultant

My experience with OMI has been devastating, Their client bumped my car and I claimed in April, Im still waiting for the claim to be paid. Moosa Nabbie is the consultant who was dealing with my claim and only at the end of June of June after numerous follow ups he sent the release form and I sent it back completed with supporting docs as requested same day. I have been following up on payment till this day and no update, today I called and was told he is on sick leave, no out of office or alternative contact in place, fine, I was referred to Nigel Pather,I expained my issue and he said his peace about Moosa being on leave I the expressed my frustration to him about the process and how long it has taken and he told me to stop screaming at him and to calm down because its not his claim, I asked to speak to me in a better tone as his attitude was escalating the matter, I told him that speaking a client or myself like that is unacceptable as it was very condescending, he then asked a question about a document and I told him that what I sent back was the release and supporting docs, he tole me that LISTENING IS A SKILL and I should learn to listen because that is not what he asked me. I then hung up because unfortunately I cannot deal with that level of disrespect in an a civilised manner. He calked again to ask if I am calm to talk and that we must talk like adults and not scream, unfortunately he has left a bad impression of OMI to me over and above the lack of service received thus far. His behaviour is appalling. I still need my claim paid. Thank you for nothing OMI and team
