illegible Numbers on lids!

I have entered the Summer competition (holidays at dream destinations etc) so many times. check my cell number -- at least 30 times. I have even purchased Coke Zero INSTEAD of Spite Zero, which i prefer, in order to enter the competition which is not available on the Sprite bottles.

I am therefore very annoyed to find that some lids have codes that are completely illegible!! I try several variations of numbers that it could be for the figures that are not clear and continue to get the 'invalid code' message on my phone. These attempts also cost me money!!!!!! I have kept the lids which would not work and I expect replacements for them please. If not, then this is ***** because Coca Cola have stated on the bottle that the lid will enable me one entry to the displayed destination. With a faulty code, this is FALSE ADVERTISING and *****.

Please contact me ASAP.
