What causes an Artery Burst - "We are offline - sorry neh"

My router is faulty as confirmed by a Telkom Technician, I went to the Vaal Mall Branch of Telkom to get it resolved and the consultant there was very rude and arrogant. Had no interest in helping because - we are offline - did not want to take my details, wants proof of purchase although I told her it is on contract! Then trying to phone them - WHAT A NIGHTMARE - they don't have a phone you have to call the call centre. It is a waste of time to talk to them!! How many people would actually appreciate a job while this consultant sits there and have this absolute attitude of I am doing you a favour by being here. Utterly disgusted will not recommend Telkom to anyone looking for ADSL lines. It is the 4th altercation in 4 months I have with Telkom and their poor service!
