Going on week 2, still no progress

Nedbank Insurance....SHOCKING!!! I opened a claim on the 20th of March, claim number C ********** 645703. My geyser in the main house was not getting power from the main DB board. A plumbing company was sent out same day, regardless of the fact that I told them it was definitely electrical relating, I however let the professionals do their thing. Plumbers found nothing wrong with the geyser so they left. Only once I called and followed up with Nedbank did I manage to arrange for them to send an electrician. 2 days later they came, again only after calling and nagging Nedbank several times. The electricians from House and home refurbishments arrived and said there is an electrical fault but before they can fix the electrical the plumbers need to replace the element on the geyser and they left. Again only after I called several times to follow up I was able to get Nedbank to send the plumbing company again, they came on the 23rd, and once again they said nothing wrong with element, this time they took pictures as proof and the guys told me that the electricians didnt want to work and made something up. It is now the 26th and I am STILL waiting for electricians to be sent again and finally resolve this issue... I dont understand that Nedbank can rely on this electrical company. Sunday I called Nedbank several times once again, they said they would send someone same day, as usual no contact from Nedbank, I waited at the house ALL DAY and no one pitched. Yesterday again, same story, I called Nedbank at 9:43 am, again at 15:36 where I was told the electrical company will contact me in the next 10 mins and if they haven't I must call them, I tried calling about an hour or so after and no one picked up. Another night without power. It is absolutely shocking!! I have spent so much money on airtime calling to follow up and beg for someone to help. Not ONE of the many consultants bothered to keep me updated regarding my claim even after days went by unless I called every time. One lady, cant recall her name, something with a M (I dont have the info with me right now) was the only one who called me back, so cheers to her!! I have spent so much money on airtime to call several times daily and been messed around for over a week with nothing done. I have tenants in the house that have been sleeping at family due to this and they are complaining saying how can they pay a full months rent if they haven't been staying there. I must make a loss and still pay R1000 excess, no, I am NOT happy. If my electrical work is not repaired today, the 26th I WILL be cancelling my insurance after they have come fixed the electric work...i am beyond frustrated...
