6 Working days to fix a business ADSL!

I have now been without internet for a day and when I called to find out when I can expect someone to come and fix the issue i have been told it will only be in 6 working days time!! How can the expect a business to run without internet for 6 days!!! Totally unexceptable. Was told I need to call back when a manager was around if I need to complain.<br> <br> This is after twice holding on for 25 minutes and then them droipping the call!!
