MTN ripped me off.

TO WHOM IT MAY CONCERN<br> On the 14th of every month MTN supplies me with R200 airtime,200MB and 25sms's which is just over R400.00 per month. <br> As I was upgrading this morning, I had made no calls or sms's or used Facebook or any other applications for the evening, went to bed and put off my data. (Roughly a year and a half ago an operator had made me aware of background data which he said I should put off, which I have). Then as I was using my phone today (15/07/15 at 6am) I had 0.00 airtime as well as 0MB left, which would be impossible because it has been less that 24hours since I had gotten the airtime and data, and mind you I had switched my data off the night before. So I don't know how my airtime and data could have drained that quickly and I've had this contract for about 18months and this has never happened before. And the operator whom I spoke to today said that I should purchase more airtime? Really that a good answer? I'm appalled by all of this, I had assumed that MTN would be a great service to use, and now I have to wait 3-5 days before I will get reimbursed or not? So my phone is practically useless! This is mindboggling and really bad service!
