Pathetic Service & *****ing people’s money!!!

I’ve been receiving a pathetic service from rain. I’ve been using rain from the beginning of this year. I have an issue that I was billed for 2 SIM cards since I did a sim swap but I was only using 1 SIM card. I keep calling them, it’s been 2months now but my issue is not attended to. They keep telling me that they’ll speak to the billing department and refund my money but I’m not receiving any feedback from them. I even spoke to the manager but still nothing has been done! I’m tired of their poor service and I’m losing my patience and also my SIM card stopped working after complaining about the issue and I’m being told that I have to pay an additional R300. How am I supposed to pay when I haven’t been refunded and when my sim card is not working, and my plan wasn’t the R300 plan! How does that make sense? I work from home with the internet and this is affecting me so much. If they don’t get to the bottom of this, then I’ll take this matter to Twitter. I have a very high influence and following and I’m sure the last thing they need is losing customers! I’m fed up!
