JOHANNESBURG - Olympian Sunette Viljoen launched a javelin into Sascoc&39;s heart only hours after the organisation celebrated the country’s 10 medals in Rio.

The Olympic silver medallist took to social media on Tuesday afternoon highlighting frustrations experienced by her and other athletes.

Viljoen, who did not attend the celebrations at OR Tambo International Airport on Tuesday, called for Sascoc to be investigated.

If there&39;s 1 organisation that needs urgent investigation, it is Sascoc. Start with R70 million donation by the Lottery 2 weeks before Rio. — Sunette Viljoen (@Sunette_Viljoen) August 23, 2016

She asked that the R70-million received from the National Lottery Commission be looked into.

Viljoen added that South African athletes had had to pay out of their own pockets to have the much-criticised tracksuits tailored for the Olympics as sizes were not taken.

Last funfact for today. Had to pay out of my own pocket for my Olympic kit to be adjusted by a tailor, because sizes were not taken. — Sunette Viljoen (@Sunette_Viljoen) August 23, 2016

President Gideon Sam also found himself in her crosshairs as she asked what part he had played in delivering the 10 medals Team SA brought back from the Games.

I have spoken out numerous times the past few years about the lack of support for SA&39;s athletes. I really have nothing more to say. Thanks! — Sunette Viljoen (@Sunette_Viljoen) August 23, 2016

Money again promised the medallists. Hope to see it within the next year. The begging is set to begin. — Sunette Viljoen (@Sunette_Viljoen) August 23, 2016
