Yet again a let down from telkom

Yet again I must take to Hello Peter to get any kind of service from telkom. I have tried calling 6 times!!!!!!! Send back and forth had the call cut on me not because I was rude but because the *********** staff could not answer my questions. I have an adsl line with telkom. Was offered fibre with vumatel through telkom. Was told vumatel would install then I would need to call with the”VT” number provided by vumatel. NOONE at telkom knows of this. Can I get some assistance please. Is that too much to ask???????
