Does missing outbound connection flight auto cancel inbound flight?
That depends on what exactly happened during the outbound flight. If you missed the connection due to the airline's fault, they should NOT have cancelled your return flight.
The airline company compensated us by providing a bus to our final destination.
Did they actually organize and paid for the bus or did you book the bus tickets by yourself and just had the airline compensate you for the expense? Either way, if you have some proof that the airline paid for the bus, you have evidence that this was the airline's fault, that they knew exactly what was happening and that you were NOT a now show.
This sounds very much like they cancelled your return trip in error.
Do we have a case here?
I believe so. As long as you can proof that the missed connection was the airline's fault and they knew about it they are indeed at fault here. The question is, of course, what to do with that. You can reach out, show your evidence and ask for compensation.
