Why am I unable to delete text messages?

[iMore Question]

i have an iphone 5c. It isn't letting me delete my text messages, When I try to delete, my phone freezes, so I have to restart, then when I go into texts, the deleted messages are still there! Once I have deleted messages I am unable to send or receive texts for ages, its like it clogs the whole system!

Sign out of iMessages and then sign back in to see if that helps.
