Upgrade done without my consent

<p>I went to Mtn Nelspruit riverside store to upgrade my 073 number that was due for an upgrade the consultant upgraded the wrong number which is 071 upon realising the mistake she cancelled it but the migration went through resulting in charges to my account. I made Several calls to Mtn without any progress until I spoke to Waseela Miller on 16 September 2016 referenced req: ********** who assured me that a refund will be madeto my account and the account will be closed which was still not done. 23 September 2016 I spoke to Sanelisiwe Mthembu who confirmed that the request REQ: ********** has not been finalized because waseela did not follow up and promised that it will be finalized. I requested to be transferred to the complaints department which did not assist.How many times do I need to call or what do I need to do for Mtn to take me serious it's even worst because I'm following up on your people's mistakes</p>
