Rain network extremely poor service and connectivity issues

It’s been three day that I have been struggling with Rain connection, I have been calling Rain and due to long wait I have been requesting for call backs and I haven’t received a single one, I’m unable to log in to the App as it’s buffering, they WhatsApp line has an auto response referring me to the App and Call Centre, I’m amazed by their poor service funny thing they never miss the deduction date.
