2 months later and Internet still not installed after multiple follow up calls

I have ordered ADSL first week of October and have paid a R700 deposit.

The guys came to install on 25 October and said they will come back to sort out the underground cabling issue which is a "quick and easy job."

After numerous calls and i was told that my matter has been "escalated". But every time I call no one sees these escalations. So finally today I was told that there is NO timeframe to fix this issue.

How can there be no frame? This is ridiculous.

Telkom, this is the worst service I have ever received and how do you expect me to wait till Lord knows when?

If you cant come install just say so, so I can cancel my order and get my money back.
