Confusing bill, cannot provide a total solution to my problem

<p>Lasy year December I called Vodacom to cancel my contract, however Maria (supervisor from the upgrade department) offered me a really good deal which made me stay with Vodacom (big mistake).</p> <p> </p> <p>For R249 she offered me:</p> <p>- R120 Airtime per month.</p> <p>- 500 MB data per month.</p> <p>- Free True Called ID per month.</p> <p>- Huawei P9 Lite.</p> <p> </p> <p>After receiving the new phone I didnt have any data or airtime, I called and she advised that the issue was "solved" however when I requested my balance (*111#) the system will show the airtime but under data it would show 5GB, Vodacom explained that I will not see the 500MB of data as I was given 5GB promotional data which lasts 1 month.</p> <p>This month I decided to login to "My Vodacom" to see my account as I didn't truly believe the issue was solved, to my surprise my "Bill so far is sitting at R407!!!", I called Vodacom and spoke to Linzy, after explaining the problem she had a "system problem on her side" and she promised that she was going to call back at 11h45... SHE DID NOT CALL ME BACK. After I spoke to Linzy I called the upgrades department and I spoke to Capsile, I asked her to put me through to Maria as I believe she needs to sort this out as she was the person that gaveme this deal and made me stay with Vodacom, Capsile advised that Maria was busy and she will call me back... SHE DID NOT CALL ME BACK.</p> <p> </p> <p>***Awesome service Vodacom, you have really awful service consultants***</p> <p> </p> <p>I decided to call Vodacom back as no one called me as promised, I requested to speak to a manager and then I was put an assistant, then I explained to the assistant to put me through to a manager as I was tired of repeating myself and having to explain my issue to everyone, then I was put through to Robert.</p> <p> </p> <p>I discussed the following points with Robert:</p> <p>1. Why 5GB instead of 500 MB allocated to me?</p> <p>2. Why My Vodacom shows that my bill so far is R407?</p> <p>3. Why the latest statement is for R229 instead of R249, and this month (May) you only deducted R110 from my account?</p> <p>4. I explained to Robert my concerned that Vodacom is not deducting the full amount and that I feel that Vodacom is making a mistake is my payment and that I am worried that Vodacom later on will deduct whatever outstading amount (due to Vodacom's mistake and not because of me not paying) all that once.</p> <p> </p> <p>After a long chat with Robert, he gave me the following answers:</p> <p> </p> <p>1. About the 5GB instead of 500 MB: he advised that I see 5GB because this promotion lasts for 3 months and not 1 month and previously advised.</p> <p>2. About the R407 seen under My Vodacom: he advised that because I have 5GB promotional in my account, the system takes into consideration these 5 GB and add it to the price I see under "My Bill so far"</p> <p>3. About the different amounts: he advised that my accout is up to date and I do not own Vodacom any amount, furthermore he asked me to contact him on the 26th of May to have a look at May's statement and see if everything seems correct.</p> <p>4. Robert advised that this will not happen.</p> <p> </p> <p>Vodacom, I really need all these issues to be solved/clarified as I do not want to have surprise bills at a later stage!!!</p>
