Airtime dissapearing

For the past few weeks I have been recharging my airtime just to have it taken almost instantly. I've contacted MTN to which they referred me to *** and almost a week later the problem still persists. They told me to close subscriptions which I have no content nor subscriptions anymore. I switch my cellular data off at work as we have wifi yet my airtime and data just dissapears.<br> The call center is off no help at all, keep transferring to another department and then I get cut off or told ive reached my limit for calling the mtn customer care line.<br> <br> Its most frustrating and Im losing money.
