THIRD COMPLAINT - NO RESPONSE

This is my third complaint for the same query - and to date I have not received any feedback ???<br> My contract will be up for renewal in a few months and I am reconsidering using MTN again.<br> <br> I HAVE JUST CONTACTED THE CALL CENTRE AND REALIZED THAT MY ACCOUNT HAS COME TO OVER R 800.00. DUE TO YORU STRIKE I WAS UNABLE TO INCREASE MY DATA BUNDLE LIMIT AND AS A RESULT I HAVE BEEN OVERCHARGED. I REQUEST THAT MY ACCOUNT BE CREDITED FOR THE DATA CHARGES- SEE PREVIOUS COMPLAINT BELOW.<br> <br> My previous complaint DD 15.05.2015:<br> <br> Good Day<br> <br> I have tried contacting your call centre to increase my self service limit ( DATA BUNDLE ) however no one answers.<br> Been to your branch but they cant help.<br> Should my bill come higher than expected I will demand a refund !
