A heart attack would be less painful than dealing with this company

I app**** for a Visa, got delayed to make an appointment for 3 weeks because of a website error in codes and zero answer to calls [lines just drop dead] and zero replies to any e-mails. When I finally got an appointment, they had a tiny messy office with broken chairs for clients... They were rude and couldn't be bothered to answer a single question. [Rivonia office]. I needed to sign my passport out for my Schengen application [Thankfully Germany uses a different, competent processing company]. Trying to get updates is a nightmare, their website tracking links just pops out errors, they do not work. Phone calls still get put down while ringing. There is no answer to e-mails for weeks. After finally getting a response I get referred to the Brooklyn office to return my passport to the application. Get there, there is no parking. The security is overly aggressive shouting at everyone like they are ********s. The visa office we get directed to isn't visible as it has a sign to a different country on it's door. Then we get shoved out the office to sit on the tiles of a roof outside as there are no chairs and they don't allow people standing inside in the hallways [in the middle of winter, as in 3 July]. When we finally get called into the little crumped office space where there are a few wonky steel benches, we sit and watch the staff hold an office party with the security for about 40 minutes [not lunch time, at 10:00 in the morning which is their office hours]. Finally one of the staff gets annoyed by the people repeatedly asking to be helped. She grabs my passport, chucks it under a counter. When I asked about the safety about my documents she started shouting at me that I am distrustful and must just leave... We are now at 12 weeks in since I app****, no reply, no answers. I need to sign my passport out because my trip starts Monday [in 6 days]. Again, had to phone about 10 times before a rude woman answered that they can't find my passport but I can just go and sit there and they will look for it then... Just not a single ounce of professional, or humane interaction.
