although oddly the Haart rep signed with the date 20th July 2015, idiot. Very much doubt I can rely on that though :-)
Why not, I would at the very least tell them you are majorly unimpressed with their performance and that in your opinion you have the right to fuck off due to the date on the contact, emphasising that its another example of their shoddy performance, if nothing else might focus their minds a bit?
Then again they can't even spell Hart so what do you expect?
