Terrible service, ******

<p>On Sunday the 25th of June 2016, I purchased R10.00 airtime and made a call for R282.00, when I dialled *141# to check my balance, some message popped up on the screen as usual "Use R365.00 to get R55 plus 10 MB Wow Bonus", I then used airtime for watsapp after running out of the wifi bundle that I have with some service provider, around 4hpm I received an sms that MTN has awarded me with a R55 airtime and 10.0MB since I have used R7.00 as per their terms and condition of this "Wow Bonus", when I checked my airtime, it was R58.54c, then I continued using watsapp, when I went to bed at 7h30pm, I dialled *141#, the airtime was R55.00 and data was 6.31MG, the data that they have given as part of the "WOW BONUS", Then I went to bed, on Sunday Morning I woke up only to discover that I had R0.00 airtime and I dialled 173 to find out what happened to my R3.00 and something airtime and I was told that it was used up by the time I was on watsapp, my question then was "After receiving the WOW BONUS R55 airtime which I didn't use, the data that I was using was MTN'S 10.0MG which they deducted and it ended up being 6.31".. According to MTN, one receives R55.00 airtime and 10.00MG after using R7.00 airtime which I did and only used their data not the R55.00 airtime. The consultants failed to tell me what happened to my R3.00 and something airtime that I had left on Saturday. MTN has been doing this over and over again. They pretend to be giving the WOW BONUS whilst knowing that at 12h00am they'll take what's left of the WOW bonus and our airtime as well. For several times airtime has dissapeared from my phone without any calls or sms's having been made. I want my airtime back and all the money that they have ****** me.. MTN says "Use R7.00 to get the WOW BONUS" and my entire R10.00 was used, why?</p>
