poor service

There was a leak from the geyser and the managing agent contracted Sea Point Plumbers to replace the geyser and they did this. However, the leak got worse once they had finished. They have been back a few times to try and fix it with no luck and the problem is ongoing after a few months now. They are now threatening to blacklist me, but the job is still unfinished. I would definitely not recommend using them. I will update this should they resolve the issue positively
