Really really really bad service

I'm so angry with these people, I have done an application on the 31 of March, every day they requested documentation which I did send, all the money I had to waste on calling everyday and mails I needed to send, on the 14th of April I was promised that my application will not expire because they have a back log and I don't need to worry my application is being processed, someone will call me within 24 hours I must please be patient because they understand my frustration, reasuring me my application is finished almost someone will call me to finalize everything. Nobody did call . Since 31 March until 14 April already. 16 April I call again to check just for this people to tell me my application has expired I need to re - apply. What the hell do these people think I'm stupid, yoh I'm so furious is not even funny.
