Zero Service!!!!

Awful service. I have a line that i have never had a sim card for. During lockdown, a consultant suggested i upgrade this line to a data line - and advised I wouldnt lose any monies available. NOT THE CASE. I finally got the upgrade reversed during June but i cannot get the line cancelled. Still dont have a Sim and have NEVER used the line - EVER!. I have escalated the matter - No manager ever calls me back. Infact, I called 5 times in one day and the calls were dropped - nobody ever called me back... I had to keep calling and waiting. I have now started emailing and still - NO JOY. It is now September and I am STILL PAYING FOR SOMETHING I DONT USE or NEED!!!! In have 4 other contracts with Vodacom which i will be moving elsewhere. SO FED UP AND DISAPPOINTED!!!!
