SIM swap request for ****** phone on a Contract still has not happened

Good Day,

After having my phone ****** on Friday, and heading straight to mtn to get an Upgrade(was due anyway) to the S9 galaxy i was told i can do the SIM swap request that day as it was to late. Sunday the 29 I went in again and requested a SIM swap on my own contract, paid for the service and was told to wait 2-24 hours. Ist not been more than 2 days and the new SIM is still not provisioned. I have tried FB, Twitter, Emailing the Store en Contact us on the website yet im still waiting while some ******** has my number.

Please assist as this is ridiculous.
