British Airwawys and eDreams

I booked at ticket on British Airways in Sept 2021 which was cancelled due Omnicom in Dec 2021. The flights were subsequently opened the next week and I bought a new ticket in Dec 2021 and paid again. I app**** for a refund on my cancelled ticket under current EU regulation as the airline cancelled. I booked through eDreams who have been absolutely useless as they just send standard replies the whole time. I got fed up and logged my own request on BA site on 03 April 22 (***0) and just get replies apologising for the delay. I tried to phone BA customer service various times to query but can’t speak to anyone, they say to try their Trade Support, who can’t help me as they only deal with agents (Edreams in this case). I called and emailed various times but they have a standard copied response. It cant take 6 months to get a refund and both eDreams and British Airways are terrible in resolving. I saw a company who fights battles on your behalf and will seek to get their advice now as am fed up!!
