On 5 March 2008, Irwing 514 CC (appellant/seller) and Mngani Property 4 (Pty) Ltd (respondent/purchaser) concluded a written agreement for the sale of a shopping centre in Westonaria, Gauteng for R41 million. Mngani paid R4 million by 14 March 2008 in accordance with the payment schedule in clause 1.2 of the agreement. Clause 1.2.5 required Mngani to provide bank guarantees for R32 million within 30 days of signing. Nedbank issued guarantees totaling R32 million on 10 July 2008, but subsequently cancelled them before registration of transfer, placing Mngani in default. During negotiations to salvage the agreement, Mngani paid a further R1.375 million, totaling R5.375 million paid. On 31 October 2008, Irwing sent a notice of default under clause 5.1, requiring remedy within 2 days. When Mngani failed to respond, Irwing cancelled the agreement on 7 November 2008. Mngani responded on 10 November 2008, alleging the cancellation was premature (believing the mora period was 7 days instead of 2 days) and itself cancelled the agreement, seeking a refund of R5.375 million.
