Poor Communication, No Follow Through

I realised I had been double charged for a license renewal and delivery, R650 about a week after the transaction - mid April. After a month I have had multiple calls and sent multiple emails. My emails have all been ignored and when I speak to the call centre support team they say they have escalated it, but there is no communication or follow through from the support agent. I have been dealing with Cathrin Mabala and on two occasions I asked her to send an email or keep me updated over the past two weeks and still no response. Nearly 6 weeks later nothing has been resolved, no communication received and no money refunded. They are supposed to be online support, but no actual support been given.
