Hero didn't get uncapped after purchase

a bit ago I bought the Dehaka commander for £3.99 I waited for the purchase and it said paid and the money as gone from my account. only to find after relaunching the game and restarting my pc Dehaka was still locked at level 5 and couldn’t progress any further. I didn’t know how to deal with it so I left it a while and decided to pick it back up again then looked at my passed transaction seeing it was removed entirely (on the blizzard website it was) so is there any possible fix for this?
