Hi I have been sent the wrong sim but iam unable to use the phone line is there anyway to contact them by Email?
when you say "you've been sent the wrong SIM".
If you are referring to its size, are you sure that it isn't one of the 3 in 1 "push out to size” multi type, that you can make to the size you want?
If not, then I'm afraid that there is no email address but you may be able to use web-chat: Help and Support - Contact Us
The advisors are often busy though so you may not get connected straight away.(use a PC or laptop and keep the page open, just refresh it every few minutes).
Otherwise you are best off calling 789 / 0345 6000 789
