No tracking of order between departmen

Received a call from technician on 24 July 2015 (date of planned vdsl line installation) to confirm that there are cable issues to be resolved before installation can happen. A follow up call was promised, never received, nor installation. Called call centre on 30 July 2015. No record of cable issues or when will be resolved. No help from technical department (thry can only track existing phone no's, not orders). They referred me back to sales, whomreferred me to the call centre (thats who I called to get to sales), they can't help as the order no was handed over to technical department. Vandalism and backlog blamed for lack of info / feedback on our order no. No managers / supervisors available to escalate matter. Can't log complaint on the website, as we need a line number. Camt get line no without installation. <br> All call,centre agents dont know what to do, no one can help and there does not seem to be a coherent system to track orders between departments. Absolute disgraceful inefficient ystem, backed up by untrained, unhelpful call centre agents.
