Once "MTN" for people, now a day light "****"

<p>I bought air time around 7pm to make an urgent call , i only spoke to the person for few minutes upon hanging up my phone call i received an sms from MTN saying i have been awarded with r100 mtn to mtn calls and free data, which would expire at mid night. Without me requesting for it and they had taken my remaining balance of air time which got me ****ed off i then called their call centre and spoke to the lady by the name of Nosipho, she told me that their system was off line and i should call again after an hour or so, which i think was just a front to get me to hang up. Only to find that when i called again after an hour my phone number was blocked from making calls to their call centre then i kept trying the whole night with no luck i left that alone </p> <p> </p> <p>Then again last night i bought airtime as soon as i got home to use it for whatsapp only within an hour my airtime was finished how? am still pazzled! and i cant get answers from MTN since my phone has been blocked to make calls to their call centre, am totally not happy with the servive i received from MTN and these were not the only incindents where i knew i had more than enough airtime only to make an urgent call and it says insuffincient airtime while i just bought airtime MTN please get your ducks in a row your service sucks big time...</p>
