Supersonic technicians are the worst

I have made more than 100 calls to Supersonic and they are not helping me, I was told that the router sim card that I have belongs to someone else hence the disconnection every month but still they haven't sorted out that problem, they sent me a new sim card but no one is willing to activate it I mean what is so difficult in activating the new sim card so I can have access to the internet? this is honestly poor service and they are so quick to debit my account but i have never had the greatest experience with Supersonic. perhaps this platform will assist in making my voice heard cause I'm tired of calling the call center and no one comes with the solution. I was told that the technician updated the system saying that the matter is resolved, which is pure lies I never received a phone call from any technician until today, are they not willing to work? are they on strike? are they not get paid enough to fix my problem? what's really the problem cause activating a sim card is not rocket science!!!!!
