phone cut off

I am extremely unhappy! My contract has been cut of . Payments have been made en still my phone is not on-line. My phone gets used for business purposes and I have been without my phone for almost a day. I have lost numerous opportunity's to contact people and there-four I have lost a lot of income. I have been phoning the call centre only to speak to one after the other *********** person. No one able to tell me when my phone will be back on. Most of the agents don't know how to help me because the are obviously not able to read that I have authorisation to the contracts account. It is not the fist time this has happend. What frustrates me the most is that one agent will tell you the line will be reconnected in the next 2 hours. The next person will tell you it will take 48 hours. The next will tell you it will be before end of the day (yesterday) and now I get told it will only be done by tomorrow! I simply could not afford to lose one more days income from my phone NOT working!
