Recurring Data

I have a sim ***). During March I received an Invoice from MTN showing that various Self Service Data was bought recurring every month and the invoice for the month came to R5222.0 I have asked 808 and been to various MTN stores to show me how I could have bought various 20gig data and other packages when on my phone I can only buy 3gig of data and during my FNB bank online I can only buy 2gig of data. No one can tell me how. Some of the data was activated in August and November 2015 and only showed up on my billing for Feb 2016. An Alice van der Merwe phoned me and listened to my problem and agreed things were not right. She game me her email address, phone numbers (none of which I can get trough to and she doesn't respond to her email address). She informed me that she will get MTN billing and Data validation department to look into my account and also send me proof of how I bought the data. To date I haven't heard from MTN again or Alice and I'm sick and tired of speaking to 808 operators. I would like someone like Alice to phone me again to discuss my issue. Email me for my contact details (***) Regards Charlene Heyns
