Simswap

I have been trying to do a simswap for 3 weeks now. I just woke up one morning and my simcard was inactive (it kept saying emergency call and I thought it was network) I went to the nearest branch and I was told that my number is being used by someone else. I have attempted to do simswap more than 3 times with no success. I need that number back coz literally everything in my life is registered in that number. I cannot access certain things in my life because I cannot get OTPs as I no longer have access to that number. This is making me so furious honestly
