I complained that they not giving me service as paid and expected, I am forced to handle my own legal matters and because of them the process is on stand still, requested documents that I need for the process to move. Today is 14 days I am still waiting for proof that they did sent documents. That not how they serious. They respond to my complaint say I must give customer care my ID. This is pure F* off
