The parties entered into a Marketing Licence Agreement in November 2010 whereby the defendant supplied fuel and lubricants for the plaintiff to sell at Chivhu Total Service Station. The agreement required the plaintiff to deposit money into a guarantee account held by the defendant as security for any indebtedness. The agreement provided that the defendant could appropriate funds from the guarantee account to settle outstanding liabilities to facilitate continuing business. The defendant effected three deductions from the guarantee account: $20,000 on 4 October 2013, $20,000 on 12 June 2014, and $43,836 on 22 October 2015, totaling $83,000. At the time of these deductions, the plaintiff's trading account had outstanding balances. The plaintiff alleged the negative balance was due to faulty equipment and claimed he was entitled to compensation for such losses. The plaintiff had previously been compensated $8,900 for loss of fuel resulting from faulty equipment in 2013. The plaintiff acknowledged his indebtedness in an email dated 1 November 2015 and proposed a payment plan. The plaintiff withdrew several claims at trial, proceeding only with the claim for refund of the $83,000. The defendant counterclaimed for $29,626.46 for unpaid fuel invoices and rentals.
