Terrible service from Vodacom Potchefstroom

So my phone was recently ****** and I decided to go blacklist the phone and get assistance from Vodacom to claim from the insurance. I followed all the procedures they had given me in claiming from the insurance and on the day I went to their store in Potchefstroom they then told me that they can't assist me because of the mistake that was done on the system from the Vodacom shop in Klerksdorp where I bought my phone. I was then advised to drive to Klerksdorp to rectify the mistake they did on their end. I tried calling the Klerksdorp branch in which some lady was trying to help me but I could barely hear her due to the party or whatever was happening in the store. It was loud and unprofessional and she also just advised me to drive to them. Who's petrol should I use to rectify the mistake they did on their end? This is truly ridiculous and they should put measures in place to assist better. I am truly unhappy and unimpressed from the service I have received from Vodacom.
