simswap query

I am very much disappointed and angry at the service I have received from MTN Musgrave in Durban , i went there to do a sim swap because i had lost my phone and gave them the required documents ( affidavit & certified id copy) and was told to use my card after 24 hours and after that 24 hours i inserted my card in my phone but the sim swap was not done , i called them and they said they forward my documts to head office i should check the following day and still nothing has been done ... i have been going back and forth for my number , as for the 135 team they were not able to help me. how does a sim swap take more than 3 days ? im struggling to work . please fix this i need *** back ...
