Missing payments

Three payments were made to my newly acquired black Woolworths credit card, which have not been reflected on my account. Despite numerous phone call s to the call centre nothing has been done about the matter. Phoning into the call centre is an absolute joke. You either cannot hear them or invariably the line is cut. Despite several promises that the matter will be attended to, nothing has happened to date. proof of payments has been sent to WFS and still no joy. The first payment was made on the 02/05/2024, the second on 07/05/2024 and the third payment was made on the 13/05/2024. None of these have been reflected on my credit card. The service is a disgrace.
