Opodo complaint: Ticket misleading information

Dear Sir Madam,

I am writing to you to raise an issue about: Travel Agents

The issue that I have experienced was: I had been trying to book my return ticket for a while. When the travel restrictions were lifted i decided to book my return ticket. When i called opodo i was told they needed an authorisation from turkish airlines to rebook the ticket. I accepted their request and never got a call back from them. I called the next day only to be told the same. I was then promised a call back which never happened again.
I called the following day and the agent advised me there was availability for the 29th october 2021 but still they required an authorisation. The agent advised me he would hold on to the seat while we waited for authorisation. Taking the information in to account, i paid another travel agent £2500.00 for my up coming holiday to turkey on the 1st of November 2021.
Today being the 20th October i called opodo to find out if they had any update for me as they still never called me back.
When i got connected to the agent, he tells me authorisation is available but seats are not available for the 29th october!
Only availability is after the 5th November.
I advised the man that his colleague provided me with ation on availability on the 29th that led me to pay for my holiday to turkey scheduled for the 1st November. I paid £2500 for a full package. He says he could not assist me further but i had to fill in some sort of complaints form even though it was their error.
I have been on the phone to opodo for more than 1 hour 30 minutes and they still cannot get a resolution for me. The so called supervisor then cut the phone as he was not able to resolve the matter for me.
I have called them again and i am online waiting again for someone to assist me for 18 minutes more!
This has left me immensely stressed mentally, physically and financially as i fear i may miss out on my holiday trip and loose my money.
I would never make a fuss if the correct information was provided, but because of their incompetent advisors i am left in this mess.
Please if someone can help me on this.

It occurred on: 2021-10-20

This meant that Financially mentally i am so so upset!!
Is this how one is treated???
Shame on opodo, turkish airlines

Get me a booking for the 29 october 2021 or refund my money or pay for the damages and losses that have occurred!!!

I look forward to your response on this matter. As recommended by Trading Standards, I would like to keep a complete record of my case.

Yours faithfully,
