Disgusted in Discovery

My mother of 81 has been with discovery insure for several years. She then had a claims multiple claims over a short period of time including a fire, a burst geyser and an underground leak in the bathroom / kitchen. However non of the above with dealt with correctly. She had to sort out the fire on her own which occurred on the DB board. The geyser they replaced but it started leaking straight afterwards and it affected the oven which is still not working since then. The underground leak in the bathroom affected the kitchen with visual damages to the kitchen cupboards and floor. Although discovery initially offered a R95000 cash settlement for the damages however it was not accepted due to the fact that the cost was unknown. Shortly after that the membership was canceled without her consent or even knowing about it. There was an objection and several follow ups which includes phone calls and emails nothing was gone. I think this is absolutely proposterous and not on at all as they get paid every month for some time now.
