I know how you feel

I have had one not ask but demand I leave fb for her, after she did not pay, I wait 4 days  & file a UPI, wait another 4 days then she pays last minute. I send item, then proceeds to tell me they dont fit and she will have to send them back, to which I reply "I dont accept returns for sizing as all measurements are in the listing", to get a message back saying... "why?"......Because its in my terms of sale!!!. Then came a demand a week later for postive fb. sheeeeeeeeesh

So OP I sympathise with you.....
