I got a Internet provider call one time, trying to tell me that my Internet wasn't working despite the fact that I was using it on my iPad while talking to him, so I told him as my Internet provider he has my email details so could he please email me the relevant information, I then proceeded to give him all the information he asked for, or so he thought, I'd have loved to see the look on his face when he tried inputting a 10 digit account code, with an 8 digit sort code along with an email address with 2. @ signs in it etc you'd have thought he'd have twigged when I gave my phone number as 123456 despite the fact he'd just phoned me on a different number.
Regarding the bad grammar and spelling, I've had genuine letters from major companies with multiple errors in them before now!
If you can fill the unforgiving minute,
With sixty seconds worth of distance run,
Yours is the Earth and everything that's in it,
And - which is more - you'll be a man my son.
