messed up my order !

I have app**** on line for my line to be moved on the 26th November , they sent me a sms saying that the technician will be coming on the 15 or something , I rep**** no its incorrect , but still the tec guy went out. I even tried phoning but u where off line , now the tec guy said when he got to a empty house, that he will log another order , coz we only moved in on the 25th. So I phoned in and still no order , I asked what they can do now since its them that messed up the order ? They escalated the matter on Thursday , today is Monday , still nothing , im using this line and this adsl for my business ! How do I run my business without internet ? will my escalation now be double escalated or will something be done as it costed me a 100 in airtime phoning from my cellphone only to have me cut off by the consultants !
