Travel Triangle — Fraudulent deduction of advance tour amount

We had booked a tour to turkey with White Rabbit holiday, Offbeat trippers through travel triangle in December 2019.Unfortunately because of the Covid 19 pandemic and the travel restrictions due to the international lockdowns and border shut downs the tour was postponed from Sept 2020 to the next available date. In fen 2021 Travel Triangle gave us 2 options, option one being forfeit 30% of the total tour cost as cancellation fees or travel within 3 months or lose the entire money. As travel restrictions were still in place none of the options were accepted by us and now the tour company is emailing stating entire money will be forfeited and that they are closing the case. This is a clear case of Fraud by the tour agency involved with Travel Triangle supporting the same.
Need a fair solution for this.
