Worst customer care ever.

My account was double deducted which was a mistake. I immediately phoned in and lady at the call centre acknowledge that it was a mistake and she will load the refund. She promised me that the refund will be done within 3 business days. 3 weeks later my refund has still not been done. I have phone atleast 6 - 10 times requesting this issue to be sorted only to be met with promises that the accounts department did work on my account and that the money would be refunded within the next 24-48 hours. Everytime l request to speak to a manager they’re busy... l don’t know with what because it’s obviously not customer care. Last week Friday l phoned again this time upon my request for a manager the lady just dropped my call. I phoned back and got through to Siphiwe requested a manager and again no manager available, it was around 12:00 and l requested that Luyanda which is Siphiwe’s hypothetical manager phone me back before 13:00. At around 14:00 l still received no phone call or communication from direct axis. I left a comment on instagram to which they responded, I was asked to leave my details and they will get back to me. however this was also just empty promises.
