Refund Taking Forever/ Terrible Customer Service

I amd International student who registered for the momemtum Ingwe students plan for my studies. My study visa was declined so I had to request refund. Chatted Momentum up and they said it is going to take 2-5working days for the whole refund process. For the past 3 weeks now they keep giving all sort of stories. Ever since I sent the refund form all I got from them is "your enquiry is ********** 61" No communication, nothing. They offer the most horrible customer service. I called them today and the call lasted almost an hour - reference# ********** 52 still without no help or solution. This is the most terrible service i have ever experienced in my life!! Momentum refund my damn money!!!
