It's OK, they've cooked up an excuse.
This excuse is straight out of blackadder or something. I got that email too. About 5 hours later I got another email. It said:
"You have just received an email which was not up to the standards of TomTom. The greeting (Dear English Bas) was in fact specifying the language of the mail followed by my first name, this should have been personalised with your name.
We apologize for this error and for any inconvenience this might have caused. Underneath you will find the correct email."
and was signed :
"All the best,
Now doesn't that just sound a little, er, "made up". The funny thing is that if they hadn't sent me the apology email I wouldn't have noticed.
