Struggle after struggle

If I could give zero starts I would. Since last year November I have been trying to renew my daughter's visa. The site kept saying error contact admin. He visa ended up expiring in December and they told us to go get her days at a boarder post . I started again with the application once they reopened in January. I got grey hairs from calling and sending emails and being sent pillar to post . Last week I succeed in an application only to be told that I can't submit documents because her visa already expired and I need to start afresh with an application and not a renewal. They told me to make a new application and apply for a refund but I must pay again because it takes 60 days to get a refund. I do the new application and make the payment . Only to find I can't book an appointment. The money was deducted from my account but still nothing happens. I spend hours on hold to calling for clarity, only to be told that finance division has a backlog and I must send an email. It's been 4 days still waiting for a response. This matter is urgent . I'm paying for a service that cannot be provided. For over 3months trying to do an application without clear information. This is truly unacceptable and I'm furious . I want answers . I want my money back and a straight forward application process. My child cannot stop going to school because of your incompetence and inability to provide a proper service and a secure website
