No help on request of information

I just woke up this morning missing R45 from my airtime balance. On calling the customer helpline, I was told I used the internet at 1am which is what used my airtime, First I was sleeping at that time, second my internet usage uses data bundles which have also been depleted along with the airtime.<br> Upon trying to attain what could have happened I was told they can not help me because I used the phone for internet by the consultant. My airtime is gone along with my data bundles (while I was sleeping), without an explanation of how, especially since my data was even switched off during that time. MTN services can be a pain. After 15 years of being with the provider, maybe its time I move on to another.
