So disappointed

So I managed to fill in one of those Kick Start cards only to find out that i took too long complete the card and was no longer eligible to redeem the bag, this was very unsettling as i was aware it was a timed thing it would appear everyone is just interested in signing you up and explaining the Discovery part where i need to visit the gym x amount for the year. The way I feel now i actually want to cancel my membership but i know i can't so i just won't renew next year.
