Terrible communication

I have started my journey with Rosebank in Nov 2022, they gave me a early bird special which was awesome and I had to pay before end Nov. Payment was made on First of Dec, 1 day delay from my side. Now I am trying to register and the payment is not reflecting on my account. After multiple unanswered emails and phone calls I am still struggling to receive my confirmation of registration. I have received a email to order my books but in the email it states that my registration has not been finalized. I am extremely disappointed in Rosebank college. The only time they where helpful was until they received my payment. Now I am worried if I will struggle with all the other info like this. Rosebank you need to up your game this is terrible. I can not even cancel my registration and ask for a refund because no one is answering, and most probably I will struggle to get my money back as well.
