Most Disappointed with the Black Friday "deals" and "service" from MTN

I saw a few Black Friday deals advertised so decided to get a Samsung Note 8. I went to the MTN store at Clearwater - terrible service - I was told "be with you in 2 minutes" - 20 minutes later we are still sitting waiting. We left and went to the MTN store at Randridge Mall. The attitude was a bit better but still far from acceptable. We asked about the free 256gb sd card - the manager says she doesn't have the cards - we must visit the Samsung website for more details! We were going to leave the shop but it was already 4pm so we decided to get the new phone even though the service was lacking. We asked about the various packages and the consultant opened her spreadsheet and we went though all the options and decided on the 5gb data and 300 mins talk/SMS. She inputs the code but the computer doesn't accept it as it seems MTN head office has removed it! I then settle for the 2gb data with 200 mins and we get 30gb free data - valid for just 3 months. I use about 1gb data per month so 30gb for 3 months will mean a waste of 27gb - WHAT A GREAT DEAL! I then ask if they can transfer my data from the old phone to the new - "sorry, we don't have WiFi, you must do it yourself at home - you do have WiFi don't you?"! Today I get an SMS from MTN asking me to confirm a Sim-swap - I reply 'Yes' but get 2 more messages with the same question - I reply yes again and again. Both my phones now work only via WiFi - neither one can make or receive calls and the mobile data doesn't work! What happened to the good service we used to get from competent MTN staff members a few years ago!?
