Poor service Netcare alberton

Had an operation on 23rd of January 2025, I was then discharged on the 25th of January. Since then I've been trying to get hold of Dr Johann L. Colemans offices to book a check up appointment with them because I'm not healing very well but their always offline and their number doesn't go through. I've been home for 4 days with no communication from their offices regarding any documentation that I need to submit for work.They said that the Dr has been in theatre for 4 days and can't attend to any of his previous follow up patients.
