Okay, in that case please use the Platinum CC for small small purchases for another two weeks..and after one month or so, do this uninstall/ reinstall trick and see what happens.
They should periodically re-release these offers based on eligibility..you missed out on the first batch and let's try for the second batch..
Or with some substantial reason we will go for X route. Please for atleast another two weeks but keep the core card busy meanwhile..
