Clientele ****

I have a policy with clientele legal which I have been paying for years and it is up to date. I have been unfairly dismissed from my employer. I reported this to clientele legal and at some stage I have been struggling to get hold of them. I have submitted all the evidence to them and they kept on asking for more documents which I have given them. Weeks ago, they told me that having a cover with them does not mean they will represent me. Today, after they have asked me for more documents/emails , they are telling me they won't be representing me and I can dispute their decision. How can I dispute their decision whereas the arbitration is in 12 days? I feel like I have been ****med for my money all these years.
