Still no response regarding additional charges on account

Good Day, i have sent various emails to Vodacom complaints dept and the most recent email on the 3rd November with no response, I keep querying the same thing and on my email i attached a copy of the account where i am being charged for my free services. My free data of R218 is first credited then re invoiced. Then its not free. I request that a senior person contact me and tell me why I'm still since i upgraded paying for what was supposed to be free data and that this urgently be credited.

Previously i was told I'm paying more because of VAT....FYI VAT will only change because the amount has changed.

I was also previously told I'm not paying for my free data, but add the value on the account i am paying for it.

I was also told that my son downloaded a monthly additional data to be debited, which is ******* because we've checked additional services and this is not so.

Please also check this on cell number ********** see invoice. It also shows that im paying for the free service. I have to download the invoices as i do not receive the accounts via email.

Please correspond ASAP as i believe this account needs to be rectified. Thanks Diane Bartlett
