Standard Bank Home Assist won't assist with damage caused by their plumbers

Standard Bank sent a plumbing contractor to my home to repair a broken geyser. This plumber foot their foot straight through my ceiling. Standard Bank then said to me that there was nothing that they could do, since they only send the plumbers out, the plumber must repair the damage. Standard Bank washed their hands of this issue.

Upon my insistence, Standard Bank then put me in touch with the plumber's insurers. More than a month of queries at the insurance company has revealed that the plumbers are not filling in claims forms.

I have sent emails to Standard Bank Home Assist, as well as their DigiCall assist complaints department to query progress and find out how to proceed, however as one would expect when one emails a bank, no reply email, nothing.

Since Standard Bank sent the plumbers to my home, I would expect that they would, now that the plumber won't claim from their own, valid insurance, pick up the case and help get my ceiling repaired.
