Help needed with Gift Cars download

I received 3 gift cars over the weekend - the two Halo ones for Rivals and one Bash2015 car. Downloaded all three, but message says there was a problem with the downloading and I must try later. The Halo Shelby appeared in my garage though, whilst the other two are just gone. AND so are the message from T10 re. the 3 gift cars which means I cannot download them. My question is - can I perhaps look somewhere else to prompt their download ? I did try SnowOwl’s hard reset and looked in the download que, but no luck. Anyone some advice, please.

No need for yet another thread on this. The information is here:

Please keep all conversation about this issue in that thread.
