Horrible Service

I have a policy with fnb short term insurance. They replaced a faultybgeyser in my Flatley on my property(I requested to use my service provider as per usual, they insisted to use theirs). They moved my geyser to the roof(-on their insistence) which led to a whole in my ceiling ( still not fixed) and water dripping into flat onto electrical which caused a big blow and blue spark. They sent their electrician which then insisted to disconnect the metervbox! My tenants had no electricity for quite some time. Eventually that was sorted but my meter box still not connected costing me lots of money Every month., Now they say the meter box is not their problem!!! They has been coming on since June. I want this matter resolved I'm a quadriplegic and not working! I've made numerous calls.ifv I used my own service provider as before we would not be here!
