Unhappy Customer

I am actually quite frustrated and disturbed by my call to Outsurance today. On Friday I called OUT to cancel the insurance policy on our car because we had sold it through Wheelee. The finalisation of delivery and payment with the dealership was to take place today, 10 July 2021, so I cancelled the insurance with effective date tomorrow, 11 July 2021. Due to some miscommunications it could not take place today and could only take place on Monday, 12 July 2021. So I called OUT and go through to the emergency assistance in an attempt to shift the date to Monday but was told that it cannot be done because the section that deals with it is closed and so basically interpreted my car will be uninsured until OUT can open their offices on Monday and extend the date. So should anything happen during that period after 12h00 tomorrow OUT is not liable so I should keep my vehicle safe until then. So under such circumstances you are left in the deep end. This is absolutely ludicrous to me and find that this is a loophole in the processes of OUT. Situations change, life happens so to be found wanting as I currently am is really an eye opener. Surely there should be some form of emergency contact.
