No progress or interest in our router delivery and fibre activation... Error upon error from sales or somewhere or the other

A Fiber line was installed through Vumatel and the ISP is Telkom. Vumatel were efficient in their installation however Telkom just does not do anything. Their call centre was called several times since the end of last month ; only to be told that there was an internal error then it had to go through credit vetting and we would get a response within 24 hours...no response at all. We called the centre again only to be told that their back office will give us a call and arrange for delivery of the router and supply a tin number and activate the line or we can call tech support after delivery of said router. No call from back office after a week, call centre agent says there is no record of the order and the call cuts. What on earth is happening? I have an order number and a vt number. Every time some progress is made the call either ends or the line is so bad and the call is dropped(phoning using the telkom network). The Telkom store at Mall of the south was of no help at all. Sales is either busy , call does not connect or they system is down. Does Telkom even care, does your system not send details to the appropriate people so that services may be offered. "Quick to bill but a snail slow to deliver". Telkom, please inform us if we should find another ISP since you guys are clearly not interested.
