Help me get back home

I need help I came to Swaziland to sell chemicals as we all know Corona left us with no jobs but we keep on hustling. On my way back on the 7th on my way back I get to total garage to fill in diesel they fill in petrol instead they damage my car as they started it instead of draining or taking out tank. The car is not starting as we speak. The garage owner is rude and arrogant. In a foreign country with no help walking by feet the car injectors needs 28k plus labour please help me raise it to can take my car back home n continue hustling.
