Puncture in Gaborone

Innovation group lack customer centricity. I had a puncture while in Botswana, across the border. I have full track record of purchasing 4 tyres at same time which I provided them. I have full record of incident of assistance by BMW Gaborone. The New tyre cost R6000 which I did not have while across the border. I opted for second hand just to get home. On my wayback while in SA side, the 2nd hand tyre got damaged because of potholes in Tosca road. My insurance sent breakdown to carry the car from Tosca to Vryburg where I bought new tyre. Innovation group refuse to pay for new tyre after requesting documentation and bank account from me, because I cannot produce evidence of first tyre which was left in Gaborone. BMW does not carry spare tyre and out of stressful situation I forgot to take pictures of first tyre. Who thinks of pictures when having such a situation in foreign land.
