I did a huge mistake by doing business with these guys

You guys are sending me from pillar to post with refund. I settled and closed your loan on the 24th and you debited on the 24th. I told that I will get my money after 14days unless if I visit the brach. I did visit the midrand branch last week and I provided all the required documents. I'll called your collections and Velile Zondi casually told me that I should dispute it with my bank at my cost or else I will get my money after 30 days. IMAGINE. She didn't even want to give me a reference number.
