4G/LTE PROBLEM ON VODACOM!

My primary number can’t connect to 4g. I’ve called VodaCom multiple times, went to more than 2 VodaCom Stores, sim swapped and I even tried to put someone else’s SIM card in my phone to test it my phone is fine. Turns out that my phone is actually fine because the only Sim Card that doesn’t connect to 4G is the one with my number. All my LTE settings are in place but still no 4G even after a Sim Swap. I don’t know what do anymore because the VodaCom consultants just tell me to Reboot which I’ve obviously done ten thousand times. I’ve lost patience and I don’t know what to do anymore.
