Unable to have OnePlus 5T Phone's screen repaired

I am in South Africa and bought a OP5T cellphone from the US. a Month after receiving the phone my wife dropped it and the screen broke. It is now impossible to have the screen repaired! I asked their support if I could purchase the screen separately and have it shipped to SA but they advised that they don't sell the screens separately. I take no issue with the fact that the damage caused is fully my fault and for my own account - I don't expect OP to pay for shipping or replace anything free of charge. Their process for repairs means that the phone must be collected from an address that fall within a handful of European countries and of course the US. Asked If I could ship the phone to ANY address worldwide (repairs and shipping for my own account) and was advised that this is not possible. Was told to send the phone to family or friends in one of the countries that they service. I now have a $ 600 phone that is useless because of a simple screen repair. SHOCKING SERVICE FROM A NEW TECH COMPANY TRYING TO MAKE THEIR MAR****! STAY AWAY!!!!
