Standard Bank - Non compliance

A week ago 29/08/2022 I submitted a claim for my gyser that is busy leaking to standard bank via email as well as I have tried to get hold of them via telephone but to my disgust you hold for minutes on end and nobody answers and I still have not received any reply to my email. Before we sit with a burst gyeser I have been trying to get Standard Bank to send a contractor out to assess our issue. To no avail have we been assisted or contacted via any sorce of communication be it sms/whatsapp/email or phone call. We lodged a complaint via Standard bank website on saturday 03/09/2022 only to receive a computer generated reply and still nobody from Standard bank has bothered to contact me. Maybe I will get a response should I stop paying my monthly premium for service that I am not receiving. Breach of contract is what I would call it.
