bad service

my sim card was swapped without my knowledge, then a port was done firstly with Cell c, then with MTN which current. I have been trying to get the number back to Vodacom with very little help from Vodacom, I was told the number will be back by the 13th December to date its not back, i was also told that there will be an investigation by Vodacom on why the number is targetted after i have requested that the number should be flagged. I am without a phone for two weeks now
