BRITISH AIRWAY - LOST LUGGAGE

We chose BA to fly from OR Tambo Int Airport,South Africa to Heathrow Int, London on the 8 Sept 2023, On arrival at Heathrow we were told that our luggage was loaded on the wrong aeroplane in South Africa therefore it had not arrived with us at Heathrow. We were then told that it would be on the every next plane leaving SA to Heathrow and that as soon as it has arrived on the 9th Sept 2023 that it would be sent to us directly to the given address where we are staying in Hudderfield in Yorkshire. It is now 21h47 on the 11th Sept 2023 and our luggage has still not arrived, leaving us with nothing but the clothes on our backs which we travelled with on the 8th Sept 2023, no clothes, no toiletries and most IMPORTANT none of my cronic medication for 3 days now, which has now become a danger to my medical well-being and health. Not being a UK resident I am not able to get my prescribed medication here. We have been try to track our luggage for days and have been trying to call Eagle Courier, who supposedly have our luggage but their contact number just constantly rings so we have still not been able to track our luggage. This has left a very low regard and anger towards British Airways, whom we trusted for not only a safe flight but to ensure our luggage is safe too. I am not quite sure how they exspect or disregard the importance of our luggage for our 2 week travelling holiday. We are supposed to be leaving for planned second destination on Wednesday and if we don't receive our luggage by then, we will be sitting in another very bad situation. It would be highly appreciated if someone from British Airway could contact us regarding our lost luggage. This is just not acceptable and I will not be leaving this situation that they have put us through here on our planned holiday. This is not the end of this story.
