Vodacom bad service

I took out a new contract online and the consultant sent me the wrong device. I returned it. Money was deducted but a month later im still waiting for a refund that was apparently processed on 14 July 2021.....i then app**** for a new contract the day after they confirmed that they received the incorrect device and they then have been keeping me on the line with excuse after excuse or like today putting me on hold for 13 min while they check on the status of my case.......vodacom is absolutely pathetic when it comes to customer service..
