No installation on date provided

So after waiting a few weeks I get an sms saying my new line will be installed on the 4th of this month (after requesting it to be moved). So I wait at home. No one pitches, I cancel plans with friends in the hopes someone comes later and again no one pitches. <br> <br> Then I tweet, I get generic responses.<br> <br> I have also tried calling the number provided to me *** in excess of 80 times on friday and today. Omesh answered ONCE! The rest of the time it's busy.<br> <br> The fact that I get the excuse that you have no contact with the technician is utterly unacceptable! It should be mandatory for him to let a customer know on the day if he can not make it and for him to then schedule a new appointment. It should NOT be my responsibility to struggle with telkoms useless contact channels.<br> <br> Now I am paying for a service I can't use and I can't send work out which is also costing me money.<br> <br> All I want is an installation date and someone to pitch on that date! I do not think it is too much to ask?<br> <br> Preferably this week to minimise the cost impact it will have on my going forward.<br> <br> Thank you.
