A & G messing around

I am dealing with Auto & General for about 8 years, never put in any claims. I contacted them with a water leak in our guest toilet during May 2020. They send somebody out to do a leak detection, plumber came out on the 26/05/2020, replace a small piece of pipe from the washbasin to the floor. Then somebody contact us and came to close & cement the wall on the Friday 29th May, on Monday 1st June they tiled the section. The plumber did not come back to do a second leak detection to see if the leak was fixed before closing the wall etc. Because the whole wall area in the guest toilet is tiled from the ceiling down to the floor, it is impossible to detect a leak immediately. We only can discovered a water leak weeks later when the water in the wall area pushed over to the wall at our front door next to the guest toilet. Because the plumber replaced a small piece of pipe and not the whole section of pipe, never came back to check on his work, the water leak is not sorted out. I did contact Auto & General again on the 30th June, send a second email on 6 July, NO RESPONSE on both occasions. After several phone calls and emails, they claim this is a new claim and I have to pay in another R1850 excess amount. They promise to get back to me before the end of the day on Friday 7th August, received two missed calls, tried to phone back. The person dealing with the claim was busy, never phoned me back. They have been told on several occasions to speak to my mother (who is listed on my insurance details and who they have spoken to before) on the home land line because I cannot take calls at work. But yet Babba Nkosi & co keeps trying to call me on my cell during office hours. I get the impression that they are trying to drag this process out. They are aware that we have to close the main water supply to the house to save water and prevent further damage to the property. This is the worst customer service I experience in my life.
