After 6 days of ****** phone cant help me with a sim swop

On the 19th Oct. they stole my phone.Ive reported it to MTN and a case number.I bought a new sim card to only make a sim swop because its my business phone.I went to Westonaria branch and Randfontein branch with no luck.Its now the 25th Oct 12.30pm and they havent activate my sim card.Ive been with Mtn almost 10 years and this is the way you treat me.I really think you people mustnt use MTN because of my bad experience with the company.Oh and by the way if you dont phone from a MTN phone you also gonna struggle to get hold of them.
