Making calls becoming increasingly difficult

[julietilly22]

Hi, I'm having increasing problems making and sometimes receiving calls. The calls often freeze and then if answered there is no sound my end. I haven't dropped or damaged my phone and I have plenty of space re storage and memory. It's behaving like a phone on its way out not a phone only 6 months old.
