Competition ****?

I upsized my meal during the M 20 years Upsize your meal competition. I upsized my meal on 18 April 2015 and according to the voucher I received I am suppose to call a number and a agent will call me back in 36 hours. This has to be done by 24 May as stipulated in the voucher or my voucher would not be valid. So my question is this a ****? How many people has fallen in this trap of upsizing their meals during lunch time and their prizes are not being confirmed by Mcdonalds. The instant prizes are totally different. Or is Mcdonalds staff claiming all the weekends away and Ratanga Tickets. Very disappointed in Mcdonalds.<br> <br> Hope I get contacted before 24 May to claim my prize.<br> <br> Nicolette Booysen
