Incorrect billing due to ***** by Vodacom agents

Is it legal for Vodacom to change my contract terms which ends up affecting my finances and credit score without my knowledge and permission. Why are you allowing your agents to do ***** with our profiles and then give us the run around instead of helping to resolve the case permanently. Month in and out, I have to call so that the same issue can be attended to. You also fail to provide me with call recordings of the supposed changes that were made. What do I have to do to get this matter resolved permanently? 1. Correct my monthly billing as per contract. 2. Remove unknown costs added to my account permanently. 3. Provide me with letter stating error corrected and correct terms of agreement. 4. Provide me with telephone recording. 5. Hold person/s involved accountable.

We are going through too much as a country to have to deal with your agents ***** and stress monthly about incorrect billing which will impact my family financially.
