Highly upset and the retentions departments service

This is my second review on Vodacom because of my frustration at the way they have handled my last complaint . So after making my first complaint on this site I was contacted by Mr Leonard Mahali from Vodacoms escalations department and he listened to my story and promised to get back to me with some feedback by Wednesday and has not even responded thereafter.I did receive a call yesterday from someone else from that same department to resolve my same complaint. It makes me think that they are not tracking and trying to resolve these complaints quickly and efficiently because it is Thursday and both people who have not called back as promised. Iam really very disappointed with the service at retentions and their clear incompetance because my request was a simple clear one that many people cant me a response to .
