Rain is a ****

How am I owing you more than R2k when I have asked for cancelation and disconnected my router due to the fact that you have failed to provide the service you promised me. Your network is always on 0 mpbs and I reported this for several months, and you did nothing about it. You even told me you don't have technicians to come and look at my problem. How do I owe you? Please enlighten me.
