Robert is set to meet with the SABC on Wednesday after a Sunday World report claimed that the presenter was in trouble for his behaviour.
Speaking to TshisaLIVE, Robert said that he simply went to work, did his job and went home.
"I wouldn't know or comment on things that have not been said to my face. I also don't know what "behaviour" they are referring to because I go to the SABC, do my job then go home. I also don't have time for hearsay," he said.
The sports presenter took to Twitter last week to vent his frustrations over the public broadcaster's decision to suspend his producer Beverly Maphangwa. He said that he would "remove" himself from the show until the matter was resolved.
