Pathetic service from Nedbank and contractor

I lodged a claim for a burst geyser, Quicktime plumbers were allocated the jog and they accepted. Three days later the plumber is trying to fix a burst geyser. Each time they come out, they repair and leave, then the geyser gushes out water. Take into account, the water loss and electricity loss. Quicktime plumbers refuse to replace the geyser as they have to replace other parts first and lastly replace the entire geyser, as I was told. The service from (Nedbank) Thando, Lerato, Dolly, Gugu and Monique is pathetic. There's no sense of urgency and have a don't care attitude. Nedbank get people who can do their jobs, stop hiring for BEE score card. As a major bank, this service is beyond pathetic. Three days to sort out a burst geyser, really? Maybe have a proper look at your contractors as well.
