Disapearing Data

On Thursday 18 February 2016 at 06:52 I logged on to the internet and logged off approximately 20 min. later. I again logged on at 10:30 and checked my data balance. this stood at 8.60GB's. At 06:52 my balance was 13.63GB's. A total of 5.03GB's had disappeared. At 10.41 I called 808 and spoke to Paul who couldn't offer an explanation. He asked me to call back after 12. I called back at 14:43.and spoke to Tembisa who advised me to call 1555. I then spoke to Manamorena who referred me to her supervisor Liza who then transferred me back to Tandeka at 808! I received 2 reference numbers, 1. *** and 2. ***. I was also told that they would have an answer in 72 hours excluding weekends! 72 hours expired at 15:25 today Tues. 23 Feb.2016, still no response to my query. My log reflects that 17.87MB's were used between 06:52 and switch off.. A further 95.81 KB's were used at 10:30 checking my balance. My calculation of 5.0GB's used in 20 minutes works out to 4.166MB's /second!! The service provided by Mtn is pathetic. and \passing the buck\" the norm. All contract holders check your balances daily! Mtn I want answers!!"
