Very Poor Service Support from Cell C fibre "Support""

Cell C fibre Support services provide very bad service for a company that cannot afford to loose customers. App**** for Fibre speed upgrade on 20 December 2021. My request still not effected. Getting calls from call center "technicians" every day without solutions. The fact that the call to support services is "free" seemingly give then the opportunity to abuse your time on a daily....test speed, forward results, the results are from so n so you have to do this and that......! How long does it take for fibre line to be moved from 25Mbps download and upload to 50Mbps? Its about statistics for Agents case opened and closed and duration......then rate the call🙄 I'm done....!!! Victor
