I truly appreciate the time and effort you dedicated to addressing my concerns, and I feel much more confident moving forward thanks to your guidance. Thank you for being such a reliable partner during this challenging time.
Was just surfing for free legal advice and out pops a message from Tembusu Law LLC. Got an immediate whats app text from Jonathan, which was very impressive. I didn't expect someone to contact me in such a short time for free advice. Jonathan asked a few questions about my case and I feedback to him whatever was relevant. After a few days, Jonathan gave me a legal firm contact that is suitable to handle my case. In fact, he said to just wait for the legal firm to call me. He mentioned short consultation should be free and fees will only apply once the lawyer thinks I have a good case to put up.
