DSL Upgrade fail

I ordered an upgrade on my existing DSL line to 20Mbps and I was told it would take 48 hours. That was on 26 November. I made 4 separate followups throughout the past weeks and every time I'm told my order is being processed and will take 48 hours. On my last followup I was requested to verify my street address (really!!???) They verify my details every time I make a followup or call the Call Center. What other pathetic excuse are they going to come up with now for the delay? I would gladly understand if they told me the truth as to whats causing the delay. Sadly on my last follow up I requested the agent to cancel my long pending order. This is poor of you Telkom. Next I'm going to permanently cancel my DSL line and seek the services of another broadband provider. Clearly you don't want customers.
