Portia Sibiya has not extended car hire despite verbal confirmation never provides feedback

I went to fetch the rental car on Friday 21 Jan 2022 and was advised that I only have the car for 22 days. However when I initially spoke to Portia Sibiya regarding the car hire she told me that due to delays as a result auto general’s internal processing procedures I would have additional 6 days with the rental car “listen to the recording”, but to my surprise when I fetched the car that option was no longer available. I initially had the car for 8 days and returned it because I could see this process of repairing my car was taking too long and I expected to have it for 28 days (22 days remaining + 6 days due to delays). I again called auto & General on 24 Jan 2022 and received verbal confirmation that the car hire extension had been done for an additional days and i would only have to return the car on Friday 18 Feb 2022, which i was happy with. I called Europe cars today (11 Feb 2022) to confirm this only to find out that extension had not been done, despite the telephonic conversation I had with an auto & general consultant on 24 Jan 2022 that the extension was done. This is the worst service I have received thus far. You never provide any feedback to any queries I have and now I don’t even know if I will have means to get to work on Monday, simply because you didn’t do your Job. Please urgently assist, this is getting out of hand.
