Rain poor technical service and customer response. 6 days with no service or response

It's six days after I received a rain Sim card and it is not showing any network signal since day one. I have called 3 to 4 times daily, send support emails and still no word frim them. The call centre staff are only trained to tell you a few things like robots: move around with your device to optimize, change APN and reset your device and send an escalation email to technical department. Technical department never responds so every time you call they take you through the same steps. It is clear that they have not connected me to the nearest satellites to my area but not even the supervisors can pick up the phone and call the technical department. The technical department appears not to even check if their infrastructure is working correctly or they totally rely on AI to decide even if it doesn't work for customers. The advent of customer care centres divorces companies from their responsibilities and frustrate and destroys the productivity of customers without compensation or improvement from these companies. They treat customers as technologically illerate while they fail even to collate a basic instruction pamphlet or leave room for complex problem-solving in their companies. The fact that customer care is not allowed to contact technical department by phone is beyond my understanding and the fact that supervisors promised to call back and never do shows very poor leadership and how companies are abusing customers by lack of access and direct communication and pure lack of professionalism.
