Horrible service that increases the problems

I have emailed my documents last week Monday as requested to support my case and after 48 hours I have started contacting them and all I was getting was empty promises or lies. Yesterday I called again the lady said the legal adviser book my case on the 6 December, after when I was harsh on her she then said she will book it to another legal advisor. Today In the morning another lady called me to said the legal advisor will attend my case after 48 hours, I did not buy those stories and this afternoon I they called me only 30 seconds and dropped, is like they was just playing with me and after send a message to pretend like I was not available, I then immediately called them and the guy said the legal adviser is busy and I should expect his call but nothing as always

Is not for the first time when I logged the complain about the poor service or lies All they do is to apologize and improve the service. They worked like I don't pay monthly or they need bribe

What i must do to get a respect as I customer?
