RCS insurance claim

I submitted a claim against the insurance policy linked to my account due to the loss of employment and income. I have now contacted RCS twice to find out what is happening with my claim. They do not read my documents and my affidavit to see that I cannot submit a letter from the company that employed me as they used a labour broker to cancel contracts. I do not know what to do anymore. They just seem ******** towards my explanations, and trying to get through to them on their telephone lines are the most difficult process.
