Worse service received ever.

I have 2 or 3different contracts with Vodacom. A week ago my fiber couldn't connect to my systems at home. I have been making several phone calls every day and a lot of *********** people promised to phone me back and get technicians to sort me out. I was promised that a supervisor will call me back but nothin happened. Yesterday after holding the line for 40 minutes I got through to an escalation officer Mujaahid Salie who promised me that a technician will come to my house before 16H00 yesterday. I waited until 17H00 but then had to leave to attend to other matters. I made another phone call today and have send e-mails but still nothing is happening. This is the worst service I've ever experienced. I want to cancel my Vodacom contracts and tell others to do the same.
