Bad service providers Standard Bank insurance

I am so disappointed in the service providers that Standard Bank provide, on the weekend we noticed that the geyser above our bedroom was possibly leaking because the ceiling had water all over it. ( We have two geysers) one in the passage one in the main bedroom, so I put in a claim and they sent a "Plumber" on Monday. They told me it wasn't the geyser in my room it was the one in my passage and proceeded to put in a new one. And oh boy then my problems started.... While they removed the old geyser the water came crashing into my passage damaging the ceiling, skylight, DB board and walls. To cut a long story short they leave here at about 2.30pm and all of a sudden I now need an Electrician and I don't have water in my bathroom which was the geyser they said was NOT the problem.... Phone them and tell them to please come back, ( sorry they can only come tomorrow). So now I have no water in my bathroom and no light's in my lounge, kitchen and dining room ( thanks to them) During the night we hear water running outside and it's the overflow pipe!!!!The electrician gets here in the morning and says the " light switch on the DB board has been blown because of the water.( Now he has to get a quote and give it to the bank to authorise) He goes into the ceiling and tells me your geyser is filling and then emptying ( hense the water coming out the overflow pipe) so he turned the Isolater switch off until plumbers can get here. Tuesday plumbers only come back and fix my bathroom water but now our showers don't want to work and the geyser is not heating up. By this time I've phoned the bank and all I get is " so sorry " REALLY" !!!!Today is Wednesday and now they say they can only be here tomorrow ( Thursday) It's just disgusting that we have been customers since 1991 and you get treated this way. But they very quick to take your monthly R1500 payment off...We have hardly ever claimed in all those years and then we must have a run around like this.... They just DON'T CARE....Every geyser I've had replaced you get a guarantee certificate with it but not according to these plumbers and not even an invoice of some sorts. Oh and the water marks in my bedroom I was told by the " assessor is old damage!!!**** haven't even had rain and there's nothing wrong with my roof!!!! I'm absolutely furious and not impressed...
