E-mail threat

[jckit666]

i have been sent a nasty email by another member  who has said in his words he will **bleep** me over and take revenge

all started when i removed his bid on an item i was selling

four months before i sold the same person some used tickets for 30-35 pounds he claimed he never took delivery of them and so i refunded him 

he contacted me after a month saying he had the items but refused to pay for them saying i should claim off the royal mail ect so i let him keep them and told him not to bid on my items again (he has ) and i retracted the sale

then i get this threat which is very scarey as i live alone and he has my address and is just an hour away

What can i do i may have to close my account
