Lost my registred Vodacom number!!

I had a Number Registered in my name, reason i registered on my name was so i could be at peace knowing that the number belongs to me. All my family and Friends had that number of mine, and one day out of the blue that number just got deregistred and just like that i lost that number. I'm deeply distressed and dissapointed at how vodacom treats their customers. now someone else has that number and i feel lost.
