Internet cut off a month in advance

we requested on 2 Feb for our line to be moved as we are moving on the 1st of March. On the 6th of Feb we get sms to say our new line well be installed on the 11th of Feb. so on the 8th of Feb we call again to say the date is wrong. No problem the call centre say we will change it. yeah right yesterday I again get a sms to say the line is being moved on the 11th of Feb. I follow instructions and sms back \no\". TODAY no internet at home. So now we call only to be told it HAS NOT been changed on the system and we have to wait for a technician to call us in order to be re-connected!!! when this person will call they cant say. no matter that we run a business from home and can no longer operate.<br> USELESS AND *********** COMPANY!!!"
