Customer care disaster

I opened an account with this company in the beginning of February 2021, I then received the router and the sim card. The sim card failed to launch, when i called i was told to wait for 48 hour which I did, when I tried again still the sim card was not working. I called again and the support staff attempted to assist me in activating the sim which still failed and they promised to log a call with their technicians. I waited another 48 hours and they did not cal. I called again and was told to order a new sim which I did, Two weeks passed and the sim has not been delivered, I sent an email and got a response after 3 days. I was told that a new sim is being ordered for me again. The worst part is that they are billing me for a service that i cant even access.
