Due Refund and lack of urgency

I’m very unhappy with Mazwe to be honest I’m ****ed off I was being assisted by a lady by the name of Thandi Maphalala I explained that they had deducted double and more on my monthly installment she asked that i send my payslip and 3 months bank statement including a copy of my ID wich I did that was on the 27th she prominently that id get my refund it’s the 2nd of June already and I still haven’t gotten my refund when I call its either she’s on calls and promises to call me back but never does people I work with have already received their refunds but I haven’t yet I submitted all the documents before them I explained the urgency of needing that money but it’s like I’m not being taken serious
