Unauthorised debit/ no feedback

I ordered a new advertised mobile service on the 20th of October 2017. My account was debited the same day with a pro rata amount. A few weeks later I got an e-mail stating that there was problems with stock shortage and there would be a waiting period. By now it was November so I had no service but my money had been deducted. I then asked them to please refund me my money as no service had been provided and there was no indication as to when I would receive my device. It took more than a month to get my money back after being sent from pillar to post. I then re-activated a 4gb mobile package I had with them seeing that I now had no internet service. They reconnected my old service and added a new service without my authorisation and then proceeded to debit my bank account for both. Upon enquiring I was told that I had asked for the new service to which I said why would if I already had an existing service. I then went to my bank and reversed the debit order. In a flash sms's and e-mails flooded in advising me of my debit order not being honoured. It's amazing how these people profess to being the best ISP in SOUTH Africa when their customer service and accounts departments suck big time. I cancelled all my services with them as I won't be subjected to such atrociously bad service.
