My first booking will be my last booking!

We rented a vehicle from Woodfords on Friday 29/9/2023. On Sunday, 1/10, we arrived at our BnB and noticed that one of the tyres were flat. I phoned the emergency number, and reported it, and the consultant said that because we did not have the tyre insurance, we needed to take the vehicle to an accredited tyre dealer on Monday morning to assess and fix the tyre. We needed to provide them with the receipt. We took the car to Hi-Q who assessed the tyre and confirmed that a patch is all that is required. They fixed the tyre, did the wheel balancing and off we went. Upon arrival at the depot on Wed 4/10, we once again reported it and provided the receipt to the consultant and even did an incident report. Today I get an email confirming that we need to pay for a brand-new tyre because "we are heading toward international standards, hence we cannot rent a vehicle with a repaired tyre". This is absolutely ridiculous! For good ness sake - we live in South Africa and the roads are in incredibly bad conditions - is this what they do to EVERY customer with a flat tyre? To top it all - they tell me I can come and fetch the old tyre once I have replaced it. I don't even live in the province where I rented the vehicle from! I refuse to have to incur this cost!
