Rain - Worst Customer Care / Support experience

I am fuming!! Upgraded to 5G and now been without a network for 3 days. My sim has been activated but the sim has not been registered on the network. All I get told by support is that it has been escalated and they can't assist. Or when support does not feel like doing their job they tell me the tower is down. I am furious as this is unacceptable. My 4G was disconnected immediately after they activated the 5G sim without it working. I have also submitted 3 tickets for support with no response!!! Worst Internet Service Provider
