Trip.com complaint: No support with connecting flight

Hi,
I was due to fly from Abu Dhabi to Catania, Catania to Abu Dhabi.
The flight from Abu Dhabi to Catania was cancelled due to weather.
A representative from trip.com contacted me in the morning about the cancelled flight and informed me that I would depart to Catania in the morning at 10.30am. I informed him that with this flight time I would miss my connection. I explained that as my final destination was to London, that I did not mind where I connected but that I needed to get to London. I expressed to the agent that there is no use in getting me to Catania because I would still need to get home from there.
The agent informed me that my only option was to fly to Catania and then find my own way home.
I contacted the agency and expressed that the website states ‘[Trip.com Self-Transfer Package Guarantee]If you can’t make a transfer due to a flight change or cancellation made by the airline, we will ensure you get to your destination, or offer you a refund.’
As it stands, there has been no attempt to ensure I get to my destination, the agent I spoke to, wasn’t even aware that London was my final destination. He then told me that he could not get me to London for four days so I expressed that I would take this option and he said ‘it’s too long of a time in Catania’. I have been completely unsupported by trip.com in this instance and as far as I can see, there are several flights on the website.
