I have not recieved a call from the manager

My issues has not been dealt with. I have recieved a call from a manager that said he is going to investigate by listening to the calls and he will contact me. i have not recieved a call from him. I called Cellc today (28/04/2015) to follow up the initial complaint on the data usage. We have done a soft ware update through WIFI with the data off and when we checked the balance it said we owe R1100 on the next bill. i spoke to Hayden from the data department and he explained if Auto updates are on it will go on host sites.He is now making it seem like i put auto updates on when i did not. The manager i spoke too was called Lerato who told me someone from the C.E.Os office will call me at 11:00am but at 13:00 i had to call back and the agent told me she is in a meeting and she will get her to call me . This company is making me run around in circles i think i should cancel both contracts and move to MTN or Vodacom i will feel more confident with their service they have a quick response when ever something goes wrong. . I have recieved a call not from the manager but from Tshepiso who did not want to give her surname or managers name , she hung up on me so i rated the service .
