On 7 February 2018, the applicant (plaintiff/creditor) and respondent (defendant/debtor), both motor dealers, concluded an interdealership agreement for the sale of a Toyota Etios vehicle for R159,353.76. The respondent's employee, Mrs Steyn, received an invoice from the applicant's sales manager's email address. Unknown to both parties, the email was intercepted by a third party who fraudulently changed the banking details on the invoice. On 8 February 2018, the vehicle was delivered to the respondent, who made payment into the incorrect bank account as reflected on the fraudulently altered invoice. The respondent then emailed proof of payment, which was again intercepted and the bank details changed back to the correct details, leading the applicant to believe payment had been correctly made. The applicant instituted action in the magistrates' court for payment. The respondent raised a special plea of estoppel by representation, which was upheld by the magistrates' court and the plaintiff's case was dismissed. The applicant noted an appeal timeously but failed to comply with various rules relating to the prosecution of the appeal, causing it to lapse. The applicant then applied for condonation and reinstatement of the appeal, which the High Court dismissed on 18 November 2021, finding no prospects of success.
