puff pastry taste old

I purchased 2 Todays puff pastry on Wednesday 20/01/16. I put it in the freezer, on Friday i took it out of freezer to defrost for about 2 hours then when i opened it the pastry didnt look right to me and it was breaking. I already planned to make apple pastry so i decided to mend it bt rolling it out a little. When i baked it i could already see its not right. It was not rising at all and when it was brown i removed it. I was so upset it didnt puff at all. It was hard n taste terrible i had to throw my whole batch away. I am so upset i wasted R30 for both pastry i wasted my apple filling and wasted electricity. I made danishes a week ago and it came out puffy flaky and delicious but the ones i baked today was terrible. I checked the expiry date is nov 2016 so why is the pastry old. I tried sending customer care an email but got a undelivered email saying recipient mailbox full cannot respond. This isnt the first time i have experienced this and just ignored it but i cannot waste my money like thid as it is getting more pricey. Very Very dissapointed
