2 days waiting for electricity technician

I have logged a call with EMM since sunday 6 September 2015(reference no: ***) regarding my main box outside my house tripping the main switch inside my house. I have been calling EMM more than 10 times a day and they keep saying the technician is on the way. Today I call and they tell me the technician came and left when they did not even supply me with the time of his arrival, how can I prove that he came. When I call to find out how is that possible, the consultant tells me that my estate street was not provided when I clearly gave it to 15 or 20 of their consultants when I have been calling since sunday. This is plain ridiculous when I only need a technician to come fix my box. What kind of service is this from their consultant when they dont even know who the technicians are, how many are deployed per area and call out from these so called technicians to confirm your address if they do ever come. 3 DAYS WITHOUT ELECTRICITY IS PURE TORCHER FROM EMM. PLEASE HELP ASAP.
