HORRIBLE CUSTOMER SERVICE FROM VODACOM

I app**** for the Vodacom VOIP line in July 2021. I received the telephone device on 19 July 2021. For 2 weeks Vodacom did not activate the line. I called them several times to ask for the line to be activated, I kept getting excuses like they cant activate because the number they gave me already belongs to someone else. I got frustrated and I cancelled the line on 30 July 2021. Despite never activating the line I was billed for it. I have also been calling them to come collect the device they gave me, but they are not collecting it. Now I am leaving home, and I am coming back end of November I have no idea what to do with the device. PLEASE DO YOURSELF A FAVOUR AND NOT GET ANYTHING FROM VODACOM. THIS IS MY 3RD COMPLAINT ABOUT THEM IN A SPACE OF A MONTH. THE CUSTOMER SERVICE IS VERY BAD
