Furious and frustrated!!!

So here i am day5 without internet.let me elaborate:On friday my dauhter phones me to tell me our adsl router is off.So we dont have any internet access,i then log the fault telephonically and they send through the ref:no to the technicians.customer service were very helpful but my beef is with the technicians that dont give a damn about my internet thats off for 5days. They said the problem has been fixed so they just need to come on my premises to setup my router again. One of them said im not at home whilst i was standing at the window awaiting their arrival. The other one that the job was then allocated to never came or phoned. CAN ANYONE ASSIST ME IN THIS MATTER PLZZZ
