Worst customer service ever

I ordered a sim card from Rain and in 5 days they had not activated. After calling logging call multiple times with no assistance, I hen decided to just cancel the sim card and for them to refund me my money. I have logged multiple calls and the only response I received was them saying they have merged my calls. Nothing has however happened. When I called in the people that i spoke to kept saying they will escalate however still nothing is happening. One of their agents even gave me a wrong reference number so when i called in again, i was told the reference number does not exist and they cant locate my communication with the. I thought Telkom was bad in terms of customer support but Rain definitely takes the cup cos honestly their agents don't even know what they are doing. I just want my refund and for them to cancel their sim card
