Landrover Backup fails miserably.

I have a 2021 Defender 110. In the last 2 weeks a warning light was activated for a low coolant level. I had to top it up every 100 km. Clearly there was a leak. I took the car to LR Centurion, where they confirmed it at the waterpump. It needs to be replaced. Landrover South Africa does not have a spare pump available and it needs to be shipped from the UK. This can take up to 21 working days. Apparently it can not be flown in, even if I will pay for it. I am disgusted that a major firm like JLR do not have spare parts readily available. Surely I am not the only one with such a problem. I tried to phone head office and left a message, client service will call me back, dont know when. Without being emotional, this might be the last reason that I will buy a LR again.
