Mytrip.com complaint: cancelation of trip without customers knowledge

On 20012020 I made the purchase of a trip to Thailand to be held on May 30, 2020 by the company MyTrip. Taking into account the pandemic situation due to the Covid 19 virus on 04042020 I received an email from MyTrip warning me that my flight could be affected and that I had two options: a voucher with the value of the trip so I could travel again or if I had already received help from the airline. In other words, in reality I only had one option, the voucher. With this information, on 04052020 I asked the agency about my options and if I could get the money back if I didn’t make the trip. To this request for information the agency’s response on 04062020 was to resend the email again citing the same two options (voucher or already had help with my reservation). Without a response from the agency, I then turned to the airline that informed me that until that date the flights were scheduled to operate normally. After receiving several more emails asking me to make a choice regarding my trip (voucher or already helped) and taking into account that with one month of preparation and the current situation of the pandemic it would not be possible to make the trip in a safe way, on 04232020 I opted for the voucher accepting the conditions that had been given to me by the agency (the trip would have to be made by both passengers and until February of the following year). Still having doubts about the situation on 04242020 and 05182020 I asked the airline for help mentioning that I had opted for the voucher by the agency and what would be the conditions to travel again or receive a refund to which the company answered both times that the refund would have to be given by the agency. On 08132020 after almost 4 months of having chosen the voucher I received by email the conditions of the voucher from the agency (where nowhere is it mentioned that I would no longer be entitled to a refund). With the progress of the pandemic and changes in my personal and professional life I realized that it will be impossible for me to make this trip since until now (almost a year after the supposed departure date) there is still no expected date to travel again safely for tourism purposes. As such, on 12182020 I contact the agency again to request a refund for my trip. On 2132021 I finally receive a response from the agency informing me that my trip has not yet been cancelled (when the flights never took place due to the pandemic) and that I could cancel the trip and receive a partial refund if the airline granted me an exception. So I contacted the airline with whom I communicated until 19022021 and who proved to me that it was the agency that cancelled the flights (without informing me) before these were cancelled by the airline which invalidates any refund from them and again informs me that the refund is the responsibility of the agency. Taking this into account, on 02232021 the agency informs me that the reason I can’t have the refund after all is that I chose a voucher when this was my only option from the beginning and more than once I questioned whether I could receive the money even though I had the voucher which was never answered or informed in any email or terms and conditions. This would have to be communicated to me before I agreed to the voucher. As such I made a call to the agency on 02232021 and after almost an hour without any answer or concrete evidence they told me that they will pass the case to the financial department and that I would receive an answer by 02262021. As of today, 06032021 I still have not received any further response from the agency. I would like to have my money refunded or at least a voucher with a more extended deadline since the one that was given to us expires on 31st of December 2021 and until June 2021 it was almost impossible to travel so e only have 6months to reschedule the trip. And of course the fault is with the travel agency Mytrip because they have canceled our flights in our name without our permission and without informing us that they would do that.
