I recently hired Slater and Gordon to assist me in solving a family matter, and they introduced me to a solicitor named LAURA FLANAGAN. On our first appointment over the phone, she seemed knowledgeable and serious, but after I signed the agreement she did not do any work about my case, neither she nor anyone from this firm responds to emails or calls. NO CUSTOMER SERVICE AT ALL. After a month avoiding me, I told her that I would denounce her lack of professionalism, and she decided to reply saying that she was too busy and that she would start working on my case. Another month has passed, and I have not confirmation or update about anything. That email for customer care is a joke; no one replies to it. The office has just sent me an invoice to pay the second part of the fee, I tried to reply asking for information about my case, and the email doesn't work either. Nobody in this company ever showed their face to solve any issue, and suddenly they all disappeared. I went to the address stated on their website at 90 HIGH HOLBORN and found out that they have officially left the building and no one knows where they moved to. I feel scammed right now. I am definitely calling the police.
