I ordered an Orange wireless broadband dongle by phone. When received,
it didn't work (never mind no reception, it wouldn't even install). I
rang to return it (within 7 days of receiving it, and under the SOGSA)
and they said they'd send me a return envelope. The envelope (Royal
Mail Special Delivery, so currently minimum £4.95, and possibly more by
weight) arrived today and wasn't prepaid and the covering letter said I
had to pay for the postage. Under the SOGSA, because it wouldn't work,
I shouldn't have to pay to return it: I wonder how many people wouldn't
know this and would just pay. I rang Orange and they said they should
have sent me a prepaid envelope. It might have been an honest mistake
on their part, or were they trying it on (just as well I know what the
situation was or else they might have got away with it!).
