I was told to arrange tunneling so that charger can be installed, I was given specifications and I did exactly according to specification provided. When engineer came he was unable to pass cable through tunnel. After that there was no response and after that I had to ring and send emails to get what is next step. e mails I received were quite abrasive that I can go and arrange another company to install charger; that meant further delays. Eventually I was give option that if I can pass the cable through tunnel they will come and install the charger. Cable was send and it tool five minutes for me to pass the cable which their expert engineer could not do such a basic job. It took another two weeks to engineer to come and install the charger which was fine. Job was eventually done but overall experience was not good and rather frustrating throughout.
