Total incompetence/mismanagement of Accounting Department

I honestly do not want to deal with these people, purely because of their terrible admin. Every time I have to go and do blood you have to pay upfront but to get an invoice, is like asking for a tax refund from SARS. I honestly think they are running two sets of books because I can never get an invoice out of them without having 3 or more emails and phone calls. You have to ask why is this? Sure you get slack admin but I have been dealing with them for a year now, and enough is enough, no one can be this slack. But I see on your site all they have is terrible reviews for the same thing. Surely they should be embarrassed by now.
