i need help from staff

It looks like all that happened is that you posted a new thread (i.e. not with the quick reply box) three times. Presumably you hit the submit button three times.

Then a staff member here merged those three threads together, making it show as three identical posts inside of one threads. Another member pointed out the three copies, but by then two of them had been deleted by staff.

No other posts of yours are duplicated, so any time you've used the quick reply function it has worked fine. Just be careful not to hit the submit button on new threads more than once
