Upset, furious, unhappy customer

Hi<br> I took at contract with MTN is April 2015. The bill ran over R6000 for 2 months and during that time the phone was not in use. I did go to the store and query and they were to come back to me. With no response i sent a mail to customer care at MTN and still no response. Sep, Oct, Nov 2015 and Jan 2016 i visited the store again and management was to come back to me. Still nothing. I also requested an itemised billing and queried my contract as i took a top up one. I called the store again today.. lets see. The biggest thing for me is that MTN listed me as a bad payer without even consulting me regarding this account. It is totally unacceptable as i cannot even upgrade my vehicle as i cannot get finance. i am so angry and upset that it is unreal.<br> I need to see exactly how MTN came to bill me those amount.<br> Jessica
