Review Upgrading

I went to MTN in Mimosa Mall to do a upgrade on 2 numbers. The numbers is ******** and ********. Last week I spoke to Palese regarding the upgrade. She ordered 2 phones, from where I don't no. She told me to come back to the shop on last Friday. I went back last Friday just to find that the system is off line. Palesa said I must come back on Sunday, which I did just to find that Palesa is not working over the weekend. Palesa gave me her cell number which I called today on numerous occasions without success. She does not even call me back. I also did sent her a SMS just to update me on what is happening. Up to now still no reaction. Is this the way MTN is treating their customers. If so I will publish it on news 24. My contact number is ********. Can someone please call me.
