Clientele is a disappointment

I received a call from one of their agents in July telling me about their new Gold Reward Plan and its benefits. Firstly the agent **** and said if you pay R250 for the Gold Reward Plan you get groceries worth R2500 every month, which I learned later on that was not the case. She then also told me that the Sim card will be delivered at my house and I told her I am working so I won't be able to receive it and then she asked who can sign for it, I told her my mother would she said that's fine. 2 weeks later I received a sms saying I should collect my Sim card at the nearest kiosk. I then downloaded their app as told and checked for my nearest kiosk which was Maponya Mall. I went to Maponya mall and found very rude agents who told me that the Gold Reward Plan has been put on hold and besides that they don't Rica Sim cards. I went on the app and used their whatsapp line to check what I need to do. A lady by the name of Audrey called and said she doesn't understand how the agents can say such to me and she will talk to the person in charge of them so it can be sorted. The guy then called me and said he will let me know when to come but never called. A week later I followed up on whatsapp and Audrey said she will get the Sim to me but still I haven't received. Everytime the delivery company will call and say am I available and I would say yes but they never come. 2 months later they still debiting my account yet I have not received the Sim card. I'm so disappointed because I even tried calling but no one helps me. I tried on Facebook and they said I will get a call within 24 hours but never got it. I just want my money I don't need the Sim card anymore such unprofessionalism is so disappointing
