FM5 VIP MEMBERSHIP, PROBLEMS WITH GETTING CORRECT CARS

So I downloaded the vip membership last week, and before i did that I had bought the Lotus e21 F1 car. I was under the impression that if I would get the vip membership you would unlock a series of cars including the lotus e21 (which is fine), and if you already had the lotus it would give you the Ferrari 250 GTO (as per forums). So i got the membership and it gifted me the lotus e21 even though I already had it! I called xbox services and they told me to check out this forum first. Any ideas on what I have to do to get that Ferrari 250 GTO? I was thinking xbox should maybe give me some tokens or something? Maybe thats too much to ask?

See this overview of gift cars:

Per the announcement: “Those players who have already purchased the 2013 Lotus E21 as of today (Wednesday, November 27) will also receive the 1962 Ferrari 250 GTO as a further thank you.”
