ZEP Schedule an appointment nightmare

MY QUERY HAS STILL NOT BEEN RESOLVED. I paid my application fees online on 19 September but up to this day l failed to secure an appointment. Each time I tried the system reports an error has occurred. My final attempts have been yielding an error message on each click on the appointment tab. I beyond frustrated with the problems l have encountered trying to book my appoint. I have send queries to them which gets very quick responses. none of their recommended actions have solved my problem. The issue is we have other things to do with little time to spare now it seems most of my time is now spend trying to get into the VSF system not to mention the cost of data. Please for everyone's sake this system has to work efficiently because it has become a nightmare for most of us.
