Stupid app!

I went to mcd yesterday to claim my mc flurry valentines freebie. I activated the voucher and it literally gives 2 minutes to redeem. while waiting in the queue the 2 minutes were up. I think its so ridiculous that there is a time limit to redeem, and what's even more ridiculous is that the instructions are not clear. I'm annoyed coz I went all the way to mcd to redeem this stupid thing and couldn't even get it. Tell your marketing team to redesign that app coz you are going to have a lot more angry customers!
