getting screw on a part from fabo no-no

no names at this point yet OK I bought something from a person on FABO here it was to be 100 % what I needed garonteed he charged me $80.00 shipping was proper for parts , I get the parts , 100 % wrong
and beat to hell. so I called him he said send back I will repay you .

ok stand uk stand up guy, I packed up the parts cost me $109.00 to send back + gas 2 hours off work you know what it takes . so I pmed him told him I Only want original price and $90.00 for shipping parts back
so he pms me a little later and says now you will het your original 1way to my door price no cash for shipping back. so he wants me to eat the $90 wich was 109.00+ and just forget about it in a PISS OFF WAY'
what does 100% garonteed right piece mean . not a 5-or 10 dollar shipping I'm talking $100.00 mabee not a lot to some people but whatever, Im pissed off at the principal of the deal if I sell you a part and tell 100% it your part your looking for and it comes here ,and its %100.00 not even close, who do u think should be responsible for the
return shipping?? now im talking it is unmoledted by me not something I took apart and yahda yahda its a 1 piece part . If I orderd red you garonteed 100% and it came blue this is how far from 100% Wrong it was not a 100% factory cast part. as stated. why would some 1 expect you to pay the$ 100.00 shipping fee to ship it back at your expense to go farther in the whole from what they garonteed you !! I am so pissed off with him right now. Do WE NEED THIS CHIT TO HAPPEN IN FABO ?? or am I just out of place . what would you do eat it or expext he man up and
pay the fee or let him tell you sorry I was wrong ??? please do respond
to get this decided in FABO. no names mentiond ,YET
