Horrible service

In the past few days I had a horrible time trying to get a 3rd party claim finalized with discovery,I spoke to multiple agents and these are the few names I could remember,I believe discovery is treating me like this because I am not their client and they feel it is of no consequence to them when they give me the run around,Your client hit into my business minibus, this might be just a vehicle to you but to me it is my bread and butter, my whole livelihood,My vehicle has already been assessed and everytime I make a follow-up I get passed from pillar to post and at times my call gets dropped by your agents,I would like to find out if I am treated like this because I am not insured by you or do you generally treat even your own customers this way...I would like to at least hear from someone as to why I deserve this horrible treatment even after the trauma that your customer caused me by driving into my work vehicle....it is totally disheartening to have such an terrible experiance, on top of suffering financial turmoil during Covid times......Kindly note this issue is a threat to my financial wellbeing....I hope to receive a response before I take extreme measures
