B&S Plumbers - Geyser

I have a household insurance however I think I probably even forget what is covered and just get stuff repaired. Coming from a home, with dad and brother having been in building construction, I learnt a lot so i generally juat fix things which i can. Well when the geyser goes then I am certainly not going to attempt that. On 23/8/2019, I reported to my nebank household insurance the geyser burst. This company called B&S Plumber's was sent to my home. I have to mention that within 4 hours of the report they arrived and kept in contact with me tough the day. Thankfully the geyser was replaced. When I got hwas from work I noticed the water had a lime residue. Well from previous experiences, I put it to the fact that the water meter was turned off and so the water will in time clear up. Well. 2 weeks later I called B&S plumbers to query this. The male who answered said that it was a friday and lunchtime and he will get someone to call back. Nobody did and we'll this could be me to blame as I had just started a new job so got really busy and actually neglected that. On the 27/9/2019 I called B&S about the hot water taps now making a real a query noise and I formed them that this is what I heard prior to the previous geyser bursting. Well I was told that the month warranty was over and I will now have to call the insurance again and that will be a second cost of call out fee. I called the insurance but made it very clear that this is clearly not normal to have only a months warranty as such on such an expensive product. B&S did send out a plumber and thankfully I got home just as he was leaving. According to the 'plumber' I will have to change washers on all 3 hot water dispesing taps as this was not a geyser issue.... it's probadly the taps that are a problem. We know I didn't belive that. I called him back to the house and showed him the water. He left after telling me that Kwikot will have to have a look. This was again a Friday afternoon last week. So has this plumber reported this yet? I have no report back. How tardily can you guys work? Knowing that you listed as a vendor for Nedbank!!
