Airtime disapearing

<p>I changed from contract to prepaid on Jan/Feb. Lastweek Tuesday/Wednesday recharged with R30 airtime and got 100 MB data for free . On Friday 03 March 2017, my airtime disappeared when I was left with R22 airtime and some MB but came back on Saturday 04 March 2017. I suspected that the reason why the airtime disappeared was that the airtime was used instead of the free mb for internet. Made few calls and on Sunday 05 March 2017I was left with R14 and 5 MB. Opened whatsapp for few minutes and after that checked my balance, boom my airtime was gone. I thought people were joking when they complained that their airtime disappears on MTN network but no…it is actually not a joke. MTN robs people of airtime period. Please fix your billing. When I phoned the call centre on the 06 March 2017 (REF:1- ********** 5355), I was told by MTN agent Petronella that there is nothing wrong with billing on my account, my data should be off if I don’t want my airtime to get used…really like I don’t know???? You can’t be the best network in SA with a pathetic service/billing like this. Please investigate as I’m not the only person who is complaining about this. I’m sure you have heard complaints from other customers.</p> <p> </p>
