***** Upgrade at MTN but they blacklist me

@MTNza since 2017 I’ve been having problems with my contract. A ********** upgrade was done in Durban using my account. I reported this at Clearwater MTN and even approached the SAPS for an affidavit. 2018 approached ICASA for assistance and they were assured that the matter @MTNza was resolved. I even have emails with all the information. 21 August 2018 I was approached by Saya Recoveries stating I owe R14392.55 , I approached ICASA and they informed @MTNza a day after I was called by an MTN Consultant who advised me that the matter was resolved.@MTNza 17/01/2019 I’m receiving a call from Hammondpole lawyers saying they are recovering R13 817.55. @MTNza sort this mess out because my profile is messed up because of the way you treat customers. I don’t even have a contract with you anymore but I’m still being abused.
