Thank you. An EV Customer representative will respond to your request as soon as possible...
You have been connected to Douglas B.
Customer:  Douglas,
Douglas B:  Thank you for contacting the Nissan Customer Service, my name is Douglas, how may I help?
Customer:  The links on the left of the web page for the Leaf no longer work, is this going to be fixed?
Douglas B:  Could you send me the link to have a look please?
Customer:  http://www.nissan.co.uk/GB/en/YouPlus/private/carwings/overview.html
Customer:  I have tried in both Chrome and FireFox.
Customer:  (a number of times over the last week-ish)
Douglas B:  Are you referring to the You + Nissan buttons?
Customer:  The links on the left:
Customer:  Battery and Charging
Customer:  Climate Control
Customer:  etc
Douglas B:  I just found out that there is a technical issue at the momment and a case has been raised.We do apologise for the inconvenience.
Customer:  At the moment,..,. For the last week?
Douglas B:  Yes unfortunately.Would you like us to send you an e-mail when the situation has been resolved?
Customer:  Yes please.
Douglas B:  Could I have your e-mail address please?
Customer:  Just setting one up, just a mo,..,.
Customer:  Can you use <<email address was here!!>> for this please.
Douglas B:  Certainly.
Customer:  Thanks
Douglas B:  We will keep you informed of the progress
Douglas B:  Is there anything else I can do for you?
Customer:  Well, maybe.
Douglas B:  Do you have any specific questions I can help you with?
Customer:  About 10% of the time when I want to initiate a charge remotely, it doesn't work,
Customer:  when it doesn't work, it won't work for many hours or a few days
Customer:  this this being addressed at all?
Douglas B:  There were issues that were resolved last week. Are you still experiencing trouble connecting?
Customer:  Yesterday morning for example. I tried to initiate a charge at 05:30, and then a number of times over the next half hour. Gave up after that and went out in the snow to do it manually.
Douglas B:  I do apologise for that.I will raise a case if I could have your IN number please.
Customer:  So does that mean that this isn't being worked?
Douglas B:  It was resolved last week but perhaps it has come back.
Customer:  What was resolved last week (this problem appears to occur at least once a fortnight)?
Douglas B:  There have been instances of customers where the vehicle was not communicating with the data center.
Customer:  That is not the problem though. In the midst of these issues, the car can trigger a "charge complete" email, so the problem is not with the comms link to the car.
Customer:  I am the technical director for an IT services company, the problems you are experiencing relate to your server infrastructure.
Douglas B:  We would like to inform you that Carwings is a work in progress,you might experience communication issues when sending requests to the vehicle but rest assured Nissan are working to restore everything back to normal.
Customer:  Well, that's just the problem really. The current situation is normal: I have had the Leaf since April 2011.
Customer:  Are you saying that there is work in progress at the moment to address the issues, or is normality going to continue?
Douglas B:  I do apologise for that, we will keep you informed of the progress of the situation.
Customer:  Which situation, the "technical issue at the moment", or the ongoing system state?
Douglas B:  The on-going situation with the system state
Customer:  OK, thanks. On the email address that I gave you above?
Douglas B:  Ok
Customer:  OK, thanks for that Douglas, that's probably all for today!
Douglas B:  Thank you for chatting with us today about Nissan Carwings, please feel free to call back any time for further information. Have a nice day.
