I need my numbers back

Hi MTN. I have lost my phone in a UBER . Let me just say an Uber driver stole my phone. I have reported to Uber and Hellopeter and nothing has been done . Okay it's fine I guess you just move on as an unhappy customer who paid so much for services and that's the Thank you you get. Okay moving right along. The reason why I'm here is because after losing my phone I tried doing a sim swap to get my numbers back because they are literally my life and have been using them for years . I bought 3 sim cards trying to get my numbers but they all failed because the Uber driver who stole my phone is using my numbers and my WhatsApp. I have called and sweared at him but he keeps using them. All my banking apps . My passport online applications . My email recovery. Everything, my life . It's all on those numbers. I'm still trying to get those numbers back or have them blocked. You are my last hope.
