Nedbank insurance

I have had a bad experience with nedbank insurance an electrical company that was send to install a gate motor that started to mulfunction two weeks after it was installed on the 4th/12/2019. The gate opens on its own randomly and that poses a security risk as it happens at any time of day or night. I have called the company that installed this motor twice already leaving my details through their voice recordings. I called nedbank today and the lady who I suspect is the same lady I called the 1st time promised to call me back the last time and today to update me, has not called back and simply told me that there is nothing she can do if the company that was send out by them is not available to come out. This company was chosen by nedbank insurance and obviously it is the bank that is supposed to find an alternative help for me to get the motor fixed. What sickens about this is that my safety does not matter and this lady/ies promised to get back to me and they have not done so. For easier Ref here is the claim number C***. I hope someone will look into this asap.
