Case ID unsolved

I have been calling customer service for days, I bought a Byod sim kit and followed the instructions and tried to port my number but had then canceled the port, however I was told my already activated 30 dollar plan could still be used with the new number I was given but customer service wants me to pay for everything again when calling back after they left a voicemail saying I was all set I am frustrated with no number or service STILL and now I’m basically being robbed because my service refill card is open on this SIM card.
