incorrect data information being given.

Good day. I am really becoming highly irritated. Last month I had Data issues with my data line and i though i had run out of data so i ended up buying an extra gig of data for the month and it took almost 2 weeks to get it activated due to your system upgrade. Then when i was in your customer care at east gate the other day checking my data it would appear that i did not in fact run out of data last month because i carried over a lot of data to this month. Now despite the fact that i have lots of data on my data line i keep getting sms's stating that i have used so much percent of my voluntary cap. somebody needs to contact me immediately as i want an apology for having to waste money on data i did not need and somebody needs to fix this mess that keeps occurring.
