REFUND HASSLE

I took a month-to-month home router with MTN, a consultant made me understand that I can cancel this contract anytime because its 'pre-paid'. I skipped a few months not paying and not receiving data (understandable). I then paid my subscription of R452 on January 25th with hopes that id receive data on the 1st of Feb. Weeks passed and i made a follow-up. I was told my subscription was cancelled because of nonpayment so the account is 'non-existent' they can't load data. No one sent me communication to inform me that my subscription is cancelled hence i went ahead and payed without communicating first. I asked for a refund, and it's been a hassle.
