PATHETIC CUSTOMER SERVICE

I've been trying to get help as my number had a problem since yesterday it says unregistered sim. I tried calling a million times to speak to a consultant but each time it's the same thing......reboot.....simswap......take to a store......and I cannot get anything right! I tried calling again and now I have to wait another 24 hours HOWEVER I can't get a clear explanation as to why!!!!!! Help me i cannot be another day without a phone
