ROTTEN EGGS

I bought eggbert large (30) eggs at Checkers in Waterfall, Woodmead on the 11 February 2016. Then I made 3, but of those the 2 were off, the yellow part was runny and looked really funny, I obviously had to throw them away. I sent an email to the Checkers management on their website on 13 February 2016, explaining, I haven't even received a phone call just to apologise for this. I have made over 10 eggs out of that 30, but have eaten about 4 roughly, coz their eggs are rotten. The expiry date though is the 29 February 2016 on the pack. This is really unacceptable, I'm irritated, coz I haven't gotten the value for my money, and I haven't even gotten as much as an apology from checkers or even come and have a look, yesterday I boiled 3 coz I wanted to have 2, I knew of those 1 will be rotten. I honestly wont be buying any eggs from checkers again.
