That's very strange, very odd.  Just to double check, when you complete all daily quests, you then have to claim the quest at the top of dailies that says completed all daily quests.  Do you do this?  Can you show us a screen shot of our daily quests after you have claimed them all?

Sorry to reply so late, I think I've solved the problem 

Glad to hear it worked out. :)

How'd you end up solving it, out of curiousity? 

Soz for late reply! I solved just by looking at completing the quests & I was completing them but cos I hadn't long started the game, I was playing for that many hours & not sleeping I got confused on how many times I completed the quests
