Unfinished claim

I am very frustrated, After my geyser replacement in July my trap door was enlarged to accommodate a new geyser, after that Standard bank was supposed to do repairs. Twice the same assessor was send in the height of Covid but no repairs were done till now today 3 months later, my kids and I are asthmatic and with winds in Cape Town dust particles are blown into the house. I called several times even went into the branch to make calls but the customer care waiting period is always too long I'm sooo frustrated I feel like there is no where to get assistance.
