Utter dissapointment with refund/finance department service - 17 weeks waiting on my refund

I have requested a refund from the 13 May 2022 - time frame that was communicated to me from Damelin/Educor was 8 to 12 weeks. It is now the 17th week, whenever I call in for my refund they just seem to have the same story "it is an internal process, will escalate, you cannot speak to the finance team, manager will escalate, will call you back (they never do I call). It is like I owe them the money the way I need to call for my credit amount to be debited to my account. I will never use the services of Damelin nor would I recommend to anyone friends, family and those who are reading this. I am utterly disguted in the way they treat their customers.
