Hi Sarah2 & welcome to the forum.
Apart from all the information on this thread, have a look at TripADeal related issues here. (< click on the blue link to take you there)
You will find many people TAD have pulled the same stunt with. One of the things you will see is that if you accept any deal/compensation from them you won’t be able to claim on your travel insurance (which I’m assuming you have).
Please keep us informed on how you go.
