Data charges incorrect

I went to Fourways Branch on 10 May 2015 to obtain my upgrade - Iphone 6. My contract was changed to the special at the time MyMTN choice 200 for R649 per month. I have always had a 2Gig data bundle on my account and Inno confirmed that she will leave that on my account. So my total contract will be around R900 per month.<br> <br> So here goes debit orders since:<br> 31/5/2015 R910.50<br> 3/7/2015 R569.04<br> 3/8/2015 R690.50<br> <br> When I checked my latest bill, 2 days ago it was over R2k! I immediately phoned 808 and the gentleman confirmed no 2G bundle was loaded on my account since upgrade?? My data charges for this month came to over R700! This is the second time the 2 G bundle was not taken into account in my billings - last year a significant correction was done on my account for the same. I am very frustrated.<br> <br> In addition, my latest bill has over R70 for international calls - I bought a R30 international bundle - which I did not fully use. In addition, I went overseas on evening of 3 July and at the time phone call centre to deactive my voicemail and activate roaming. He indicated that it would be activated within an hour. It was only activated the following Monday!
