Crossed Landline , No Internet

My telephone and internet lines have been out of order since 25 Jan 2016, Ref No 1359CRK250116 , Escalation No 819903 , I have phone the call centre EVERY day only to be told the same thing - the fault has been referred to out technical division and NO ONE can tell me how , when,or if this fault will be resolved . There is absolutely no one to speak to , the Call Centre Agents all tell ne the same thing , there is no Supervisor or Manager to speak to. Regards D Griffin
