Bent S5 Bend in phone topic

Hi brought my phone at Christmas, been carrying around in otter box defender only to find when taken out today the phone is quite noticeable bent. This can only be seen from the side.
Is there anything i should now be worried of anything that will make it more susceptible to damage now? And if there is any way or service available to quite litterally bend my phone back into shape! I thought this was an iPhone thing! Thanks - Tom
