The plaintiff, Southern Diesel Services, was in the business of supplying bulk fuel. On 1 January 2011, the plaintiff entered into an agreement with Jahedd Fuel Trading Inc (registered in British Virgin Islands) to distribute fuel in Zimbabwe and collect payments from customers, as Jahedd could not do so itself due to fuel supply regulations prohibiting foreign entities from distributing fuel without a local partner. In pursuance of this arrangement, the plaintiff collected 38,000 litres of diesel from BP Beira and delivered it to the defendant at its fuel garage in Mutare on 4 February 2011 under Waybill Invoice number 1236. The plaintiff raised a Jahedd invoice for US$45,865.00 for the fuel. The parties had been doing similar business previously, and the defendant already owed money for previous fuel supplies. The plaintiff debited the defendant's account accordingly. When the defendant failed to pay the outstanding amount on its fuel account, the plaintiff sued for US$36,172.00 (later amended to US$31,979.83). The fuel order was received from Shelly Lock, who was acting as an agent of the defendant. The defendant had made several instalment payments into both Jahedd's MBCA account and the plaintiff's NMB account towards its indebtedness.
