Vodacom usage report doesnt match invoice

Your invoice shows that in April I have data usage, call usage along with a R1 sms. Calls are at rated at almost R400.<br> How on earth does this happen that I have rated calls if I have over 26 minutes of Talk Time still in April? Are your CDRs not taking into consideration the Talk Time I get on a monthly basis? How on earth does this work?<br> I have over R200 of rated data. However, your usage report shows that I have 0 rated data sessions because I have purchased data bundles. <br> You have billing discrepancies here. I need this issue to be fixed before we have more issues. If it is not fixed, I have this feeling that I may have again another overestimated bill come month end.<br> When you send me an invoice, I want to see Time and Date of when the data bundle was activated. Simply listing an open ended data bundle does not give me recourse if there is an error on Vodacom side.
