Billing ****** and Bad Service

Good day, so I have no choice but to post a comment here due to the fact that I have no response from Vodacom via email and telephonically.

My contract I signed for is a Smart top up M This package was R499 per month With CLI R509 I added a data bundle at R 86.96 Total R595. 96

I have debit orders going of to the Below values R626. 66 R619.48 R625.30 R641.49 R625.98 R628.15 R627.75 R538.38 R517.97

If I am not paying for a device as it is free on my Package.... Then why is my balance always changing. If I signed at R399 or 499 for 24 months it should not change at all No one seems to want to attand to this, so hopefully now I will get a response
