We had 2 new meters fitted in early March of this year. Whilst the engineer was fitting them, he was on the phone to his colleague - and appeared to be having a lot of problems. He explained after fitting them, that I would have to contact EDF within a week to arrange another engineers visit, because the meters were not connecting to EDF .He did not want to leave a display unit but I insisted that he did as it would still connect to the meter and show me what was being used. I then rang EDF a few days later to explain that the meters were not connected and to arrange another visit as instructed by the engineer. The lady on the phone did not take on board what I was saying and advised that the meters would automatically connect within 2 weeks. After waiting around 3 weeks I rang up again and was told that the meters would connect automatically, but it would be a week or two.  2 months after the meters were installed I have now today rang  a third time.  I waited quite a long Time in the telephone queue which appeared to start again I eventually got through and spoke to a man. I explained to him that the meters were still not connected and that I would like to make a complaint.  The man advised me that he needed to go and get more details and asked if I could hold - which I did. 5 minutes later I heard an automatic response asking me - how would I rate my customer experience etc. The line then went dead. I rang up again - waiting yet another 10 minutes, following all the correct prompts. After about 10 minutes the music stopped and then I was asked all of the same questions that were asked of me in the first phone call. Effectively kicking me out of the queue and starting again. This happened on the first call but I then realised the pattern. I believe now this is a way of reducing the waiting times and that the wait times do not go over their targets. I eventually got through to a young lady and explained that I would like to be out through to a supervisor and make a complaint. She went away and came back to advise me that the supervisor was on their break.  I explained that there must be more than one supervisor and requested that she put me through to someone else. She said she would raise the complaint whilst waiting for the supervisor to become available. She did this and then said that she would pass me on to a supervisor. A woman came on to the phone and was immediately abrupt. I asked her how long they had to deal with a complaint before I could escalate to it the ombudsman. She stated 6 weeks - again very abruptly and said that I needed to send them a photograph of the meters.  I said that was irrelevant and tried to explain the reason why, but she continued to talk over me and raised her voice louder. I asked her politely not to take that tone with me and attempted to explain that I had been waiting for over half an hour. Throughout this time it was quite clear that she was trying to fabricate and give the impression that an argument was happening- when there wasn’t. No matter what I tried to say she continued to shout at me. I asked her at one point to stop this but she carried on. The line then went dead.  At no point was I rude or abusive to her or any other staff. When arranging the meters I spoke to a call centre which I believe to be somewhere in the Uk. However, my recent experience with this customer service centre has been horrendous. They are tricking your customers and chasing targets rather than helping people.  I have lodged a formal complaint and will be looking at leaving them as soon as this is completed
