Starbucks Trial offer

[artyg]

Spotify Team,

                       Okay so here's the deal, I was just sent an link from the good folks at Starbucks Coffee for a 3 month free premium subscription to your service, I followed the signing up process entered my info but when I clicked done it said I signed up for a 1 month free subscription (not sure why). So I canceled immediately., but when I went to sing up for the link again I was not eligible.  Is there anyway to reset this from your end,. the link is only good for 4 days.
