Data and airtime ripoff

<p>I recharged my cellphone last night and bought data. I browsed the internet for sometime then went offline and madr one call. Later inbthe night when i tried to make a call they told me i have 0.00 balance. When I checked the balances they send me an sms to say i have 0.00 airtime and 0.00MB data. When i call the call centre they tell me i was online from 5:45 until 11:45 and unfortunately they are lying because i was busy doing assignments and watcging TV also. I want my airtime and data back from mtn as this is not the first time they are doing this even last year i was doing the me to you transfers and they were not crediting my daughters cellphone number. MTN should stop ripping ua clients as we also work hard for our money we dont just pick it up for free. I want my data and airtime back.</p>
