No joy - ADSL to Fibre

We app**** for fibre through Vumatel and after the installation was done by Vumatel we received an email stating that our line has been activated. We were told to get in contact with Telkom to do the change from ADSL to fibre.... what a nightmare! I have been calling the sales department on 10213 everyday for the past 2-3weeks with no joy!!! Every time I speak to the agents I hear a different story as to why it hasn't been switched! Supervisors are never available to talk! With that being said, I have called a few times everyday and since last week, Telkom's systems has been offline for 4days! This is a service provider and they are expected to assist but they are forever offline! The call centre agents are rude and seems that they don't know how to assist people with problems! Telkom wants to be competition for the other service providers but they can't even switch a line from ADSL to Fibre! I am at my wits end and have no idea how to get this sorted! We receive text messages stating we will be billed pro-rata... BILLED FOR SOMETHING WE DON'T HAVE???
