Body repatriation to Zimbabwe

My name is Mrs Siphilisiwe Ndlovu. I currently reside in the UK. My son, Sisonke Ndlovu, got a scholarship to study Civil Engineering in Poland. He started in September 2017. Sisonke was a minister of the gospel of Jesus . He was known as Prophet Sisonke. Sisonke fell ill 4 weeks ago. He was diagnosed with pneumonia. He had acute shortness of breath. He was transferred to the intensive care unit for ventilation. This required him to be put in a coma. His lungs deteriorated. He sadly passed on on the 4th of February 2018. The family wants to repatriate his body to Zimbabwe. His insurance doesn't cover those costs. We need up to £8000 for repatriation.
