The plaintiff (Zimre Property) leased Shop No. 5 Zimre Centre to the first defendant (Saintcor (Pvt) Ltd). The first defendant, through its Managing Director John Shumba (second defendant), failed to pay rentals from December 2008 to about August 2009. On 5 August 2009, John Shumba wrote a letter acknowledging an outstanding debt of US$30,000.00. Plaintiff instituted proceedings on 19 October 2012 for rental arrears. Defendants raised prescription as a point in limine, arguing that the last acknowledgement of debt was on 5 August 2009. Plaintiff relied on a letter allegedly written by Annet Mbedzi on 22 October 2009, purportedly as Financial Director of defendants, acknowledging debt and promising payment by 10 November 2009. Defendants denied that Mbedzi had any authority to acknowledge debt on their behalf, stating only John Shumba and accountant Fungai Danha were authorized to do so. Defendants claimed Mbedzi was not an employee and that the letter was not authentic.
