Limpopo provincial government spokesperson Kenny Mathivha said government had no role in the funeral.
"We have sent our condolences to the family for his untimely death and it was unfortunate. However, government had no role to play in his funeral," Mathivha said.
Friends and relatives described Khosa as someone who wouldn't hurt a fly.
His former Khesethwane High School teacher Refilwe Ramothwala described him as a humble person.
"I really don't know what transpired when he was killed but I know he was not a confrontational person and not easily provoked. He laughed a lot and was neatly dressed all the time," Ramothwala said.
Khosa, who was a Mamelodi Sundowns supporter, was said to be a decent footballer as well.
His expensive coffin was ferried to the graveyard by a Mercedes Benz Viano, tailed by three Porsche Cayenne SUVs. His tearful wife Nomsa Montsha looked on helplessly as the coffin was lowered into the grave.
"That coffin is expensive, we couldn't have afforded it. A good Samaritan in the form of the EFF paid for the coffin," said a grateful Lesta
Shadrack Khosa, a childhood friend, said: "I support the family and they must seek justice for Collins and those who killed him must pay."
Collins Khosa is survived by his wife and three children Wisani, 13, Loveness, 12, and Gift, 10.
