Everything is silent after I've paid them in full

Can someone from Rosebank either finalise my registration or cancel and refund my money since you are able to process my registration in a timely manner. Classes have already started, and my registration is still pending. I have paid in full for the year and submitted POP and all documents. I have emailed several people including RC assist and I'm getting no response. I will instruct my bank do to do a chargeback on my card for non-delivery of services if you do not get this sorted ASAP!
