Appalling service DAMN MTN

Topped up my phone yesterday at 8:30am and made one quick call that lasted for 17sec and to my surprise my credit was finished.<br> Rebooted my mobile but that didn't help so I had no choice but to ring their call centre, the agent that I spoke to said the system hasn't updated any phone activities this was after 2pm. She asked me to ring them back later. After 8pm I placed another call and this laud guy said he could see the credit that I topped up and the short call but there aren't any activities, he then I must call after 8:30am the next day and if the records still don't show anything they'll refund me. Spoke to Buhle OMG!!! She didn't assist me at all she basically didn't do or say anything. She said the systems are down and they are NEVER given a time frame on when they'll be up and running again. What is the purpose of their ****** call centre when their agents are clueless!!!<br> I hate this network it's messing up my business, I've lost so much money for the past two days because I needed to make calls and I can't top up again seeing that I don't trust them anymore.
