I need my refund

I paid R600 in december 2018 to get my transcript through this company because they advertise on their site that they also assist with UJ transcript which i needed to register with Unisa, after the system couldn't allow me to order a transcript i sent an email regarding this to get some assistance and i received a response from a ''Ronel Booysen'' stating they no longer assist with the UJ, i asked her regarding my refund she said she will forward my details( account number& query) to somebody in accounts, i have followed up with her and it's been almost 2 months and she hangs up my calls whenever i call her, i want my money back.
