Bad customer service & no communication!!!

I was called by Directaxis several times in 2017 and offered a loan, and the I eventually took the loan in August 2017, I got retrenched in September 2018, and I emailed my retrenchment letter to them on the 14th Oct, I did not get any response, I then followed up on the 29th Oct, then I received an automated response saying a consultant will contact me in 2 working days, either via email, sms or telephone. To date I have not been contacted. Then on the 31st they debited my account and found nothing because I have no income, then they start sending me messages about the loan account being overdue. When are they going to respond to the retrenchment letter email I sent them? I am so furious right now, because I was charged for insurance on the loan, but now I'm getting 10 smses per day regarding the overdue loan!!!
