Dear Mr Dunstone
I am having on-going intermittent problems with my talktalk email accounts. I can send emails ok but for the vast majority of the time I am unable to receive emails from each of my four family accounts. I have tried your webmail system on my own and other computers and also mail2web.com but to no avail. This fault has been going on for nearly a week and your customer services department doesn't seem to be able to sort things
Dear Mr XXXXXX
Thanks for your email. Our email service is not actually down but is struggling with capacity. If you log on via our website, it takes a long time to load, but does actually work, I have just tried it myself. We commenced a huge upgrade last night to move it to a much larger platform which will put an end to the these issues. This should be completed by the end of the week and the problems should disappear.
I am very sorry for the inconvenience, I have engineers working 24 hrs per day to try to get this work done as quickly as possible.
Regards
Charles Dunstone
