iPhone 5 Update 7.0.2 Sound Notification Issues

Hello Apple support,

my wife and I both have iPhones 5 and after the 7.0.2 update we are having issues with iMessages getting stuck and not being delivered nor sent.

Also, on normal messages/texts my wife's iPhone 5 is NOT getting any sound notifications when someone texts her.

And, the normal messages/text are sometimes not being delivered to people at all...

Please make a usefull and fixed update soon, or let me know what I can try to fix this issue.

Thanks
