Can I file a case against an immigration consultant for not doing any action?

I have submitted my immigration documents to a consultant company in Dubai for Canada under a working visa. They committed that the process takes months but they have not yet processed it.

I asked for a refund. But they said it will not refund as it is a voluntary withdrawal within the process which is written in the contract. However, I keep reminding them the process for Candan has not yet started.

In the beginning, they said that once I submitted my IELTS certificate, they will start to find a job offer in the market of Canada. But I did not submit the IELTS certificate. And they never approached me about this.

They keep making false promises they will check and will fund soon. I Have asked several times to connect me with the higher authorities to resolve my issue but no cooperation from their end.

I have paid 6000 DHS so far. I need to know if I can claim all my money back legally.

How can I make them fulfill their commitment without me bearing any loss?
