MTN ZAKHELE FUTHI INCOMPETENCE

I bought shares when the new mtn zakhele futhi scheme was launched. I have been trying to sell those shares to no avail. I am taken from pillar to post, they don't want to activate my share trading account. since 14 April 2020. now I have shares I can't sell. they are failing to link my mtn zakhele futhi shares with my nedbank stockbroking account. MTN does not care about its customers, it is just the same as Vodacom.
