Why such a hurry, and then no news for days???

I hate people who try to abuse you into doing something -i.e., pay off a credit note for some returned goods, at work: They email, fax and phone you threee or four times a day from the other side of the world, and when you finally get your boss to agree, then there is something missing -IBAN number? VAT number? ACCOUNT NUMBER???- and, as you´d gladly email something like "As soon as you give me the fucking account number, I shall pay you the 50 euro you have been complaining about" (it spells out slightly different, but they get the tone) -they suddenly dissappear! No further news in ten days!!!??? -HELLO, ARE YOU READING THIS, MS. VINA???

Oooohhhh, the joys of Customer Service...
