Struggling to find legal advice in Germany.

Hello. I've been trying to find genuine legal advice in Berlin for a month now, but every single lawyer I have emailed has refused to take the case, citing their lack of capacity. Or, I simply do not hear back.

I purchased a defective product from Dell for 2,000 euro and now they're refusing to give me a refund after 2 failed repair attempts. I tried to educate myself as best I could about German consumer law, and from what I understand, when a defect is discovered within the first year, it is automatically assumed to be manufacturer defect unless definitively proven otherwise. This defect was discovered at month 6, and resulted in total system failure by month 9.

I also read that the customer gets to decide whether to replace or repair. I chose replace, Dell refused.

I also read that they are legally obligated to make the customer whole within a reasonable amount of time. It has been 3 weeks since their 2nd failed repair attempt, and have not acknowledged that I demanded a refund or made any substantial attempts to offer replacement, repair, or refund. They just tell me they're "Still working on it." every other day. When I ask what that means, they just repeat the statement.

I submitted the issue for arbitration, but Dell refused to participate.

I don't know what else to do. I've tried contacting lawyers, I've tried getting arbitration, I've tried asking around, but Dell is ignoring me while keeping my money. And I can't find anybody willing to help me. I don't know where to go to ask for help. I'm out 5% of my annual wages and I don't know what to do about it!
