Poor Service and Attitude

I am extremely appalled by the poor service by Mtn call centre (808). I renewed my contract in January. Upon renewal, apparently according to Mtn call centre staff a limit was captured onto my contract. As a result I can not make any calls due to a limit on my account. I did not request this and historically have never had this.<br> When I called the call centre on 07/12/2015, I spoke with Kabello who informed me that she had removed the limit and all would be in order after rebooting my phone. She said that she would call me back to check if it's fine but never did. After rebooting and releasing that I had the same problem. I had to incur costs again by calling Mtn from a Vodacom (Couldn't call the 808 Call centre as well).<br> This time I spoke with Sponsor who maintained that she can not remove the limit as the new contract is structured in this way but she can assist in extending the limit to as large as I wanted. I was then advised to fail *141*5# & choose the option to increase my limit of which I did only to release that this does not work. The long short of it is that I called numerous times thereafter asking to speak with senior people but nobody seems to help. Poor service Mtn.
