VFS Qatar, priority service visa delay. End of 21st day and yet no update!

I app**** for tourist visa to UK at VFS in Qatar on 6th of February, paid for priority service almost 200 British Pounds and was told by female officer there that my visa will be ready within 5-7 working days and usually it takes even less, so nothing to worry about. I have mentioned that I have travel plans to Istanbul on 21st of February and want to make sure that I will have my passport before my intended travel date. Officer assured me that I will have it within 5-7 working days as I’m paying for priority. After 7 working days, no news, no passport. I went to VFS and asked them - where is my passport and what is the status? No one had any idea. They gave piece of paper with emails where to complain however these emails got nothing to do with my visa! I came again after a few days, asking same question - where is my visa and where is my passport. They have no clue and can’t do anything about it, telling me that priority service takes 5-7 working days and they don’t know what is happening. So if officer knew that I have to travel to Istanbul and visa might take more then expected why it wasn’t offered to “keep my passport” service which cost 50 pounds instead of priority? Because of wrong information I got from an officer, I had to cancel trip and it cost me 3000 British Pounds as everything was non-refundable. Only because officer assured I will have passport in time, which is absolutely wrong and you should tell truth to your customers. Two days ago I checked their VFS website and it was written “that there is delay as a result of disruptions to courier routes in the region”, however I was told that my passport is in the application center and decision is done by UK embassy in Qatar. So comes a question, disruptions of which routes? My passport wasn’t send anywhere, it is still in the same application center. My documents were not send by courier, they were scanned and send online. So what is the delay for? Today is end of 21st working day and I still don’t have my visa and my passport.
