Alan Knott-Craig

Makate took the case on appeal, and then took it to the Constitutional Court. In April 2016 Justice Chris Jafta found in Makate's favour and against Vodacom, overturning both judgements and finding that Geissler had had the authority to promise compensation, and that Makate's case was not based on an unpaid debt. In his judgement, Justice Chris Jafta had harsh words for Knott-Craig and Geissler. Among other things he said : “In not compensating the applicant [Makate]… Vodacom associated itself with the dishonourable conduct of its former CEO, Mr Knott-Craig and his colleague, Mr Geissler. This leaves a sour taste in the mouth. It is not the kind of conduct to be expected from an ethical corporate entity,”

A 2014 judgement in the South Gauteng High Court supported Makate's claim to having originated Please Call Me. The court heard that, in November 2000, Makate had shared his idea (initially termed the "buzz" idea) with Philip Geissler, then board member and director of product development and management at Vodacom. Geissler had agreed to give Makate a cut should the Please Call Me innovation prove a success. Makate's witnesses presented emails sent by Geissler and an article in Vodacom's "Talk Time" internal newsletter which acknowledged and praised Makate for his idea and his contribution to the product.

In 2008, former employee Nkosana Makate took Vodacom to court, claiming that the profitable Please Call Me message service was originally his invention and demanding compensation. Eight years later, Makate eventually won his case in the Constitutional Court (the highest court in South Africa). Makate will now enter negotiations with Vodacom for a 15% cut of the R70 billion he claims 'Please Call Me' has earned for Vodacom since its inception.

Prior to 1993 he was Senior General Manager of Mobile Communications at Telkom SA, before he moved to Vodacom. In 1996 he was appointed CEO of Vodacom. He held that position until he stepped down in 2008. He also served as an Independent Non-Executive Director of Murray & Roberts Holdings. He was appointed to the Murray & Roberts Board in 2008. He served as chairman of the health, safety and environment committee until 2011. In 2012 he joined Cell C as its CEO until he stepped down in 2014 due to ill health.
