Too many 'technical difficulties'

This Embassy has many problems. In September 2017 my visa was delayed because of a power outage and then no internet. A week later I received my visa... 4 months later the Kazakh immigration will not allow me back into Kazakhstan because my visa is incorrect. The Embassy typed 2107 instead of 2017. So I have to return to Pretoria and have them fix their mistake. The problem is that their phone lines have been disconnected. Telkom has confirmed this. There is no way to contact them. My company and I have sent emails to them expressing the urgency of the new visa with no answer. The Embassies' opening times during the festive season are only a few days and if I do not get my visa during this window, the financial costs of rescheduling my flight, plus no work no pay policy of my company, equals a huge financial burden for me. Why is it so hard to have a working phone line and communicate with your customers?
