No ADSL internet and unable to help...

Problems started on Friday when I received a notification that i was now a high usage customer and I will be throttled on my uncapped line which is funny because I have had adsl for almost a year now and have not done anything different this month. After I had to call the call center and finally get the line unblocked i had internet for a full 24-hours before it went off again and it is still off.... I tried calling the help desk but was greeted by a out of office hours message until this morning i could finally get the problem logged and the phone technician helped but couldn't find anything wrong and told me he would send the problem to the technical department and received a reff number: 21CRK010615 and someone would call me. However I still have not heard anything and called in again just to receive the same news. I work from home so without internet I am unable to receive income and I can't wait 5 working days for a solution this means I am paying for a service and losing money because i can not work without internet.
