Did you SIN-LHR seperate to LHR-SIN? If so, can you not just cancel it yourself online? The agent may have only cancelled the outbound.
I guess this is the risk you run if you book non connected tickets (fully realise in your situation you couldn't though). A family member had a booking of MEL-HKG-LHR return booked for after April in J, with MEL-HKG on QF A330 and HKG-LHR on BA 777. BA changed flight times slightly and then it was no longer offered as a QF codeshare. Qantas first offered to rebook as a straight BA code, but had no problems changing the booking to be MEL-DXB-LHR return all on the QF A380, even though the discount fare code was not available.
