DISGRUNTLE CLIENT! MY PHONE IS NOT WORKING PROPER!

I hope that i am emailing to the right department. If not, could you please forward to the complaints department had recently purchased the AG Mobile Swift, on contract, from one of your clients. First let me explain what peaked my interest in your mobiles. I loved the fact that it looked and seemed user-friendly, and being someone who comes from using Samsungs, i saw quite a similarity and i liked that, cos i dont want to struggle with technical issues when it comes to cellphones.<br> <br> After having received the phone, i inserted my existing sim card, with the new sim card and a 2GB SD card. All seemed to go well. But as time went, i noticed that my phone had a tendency of freezing for no reason. Whether i was on whatsapp or Facebook or any other pre-loaded app. At first i did not think much of this, but now it happens on a regular, daily basis. And it seems to happen whenever i either change my connection from Mobile Data to Wifi, and this has become very annoying.<br> <br> I SENT AN EMAIL TO AG MOBILE DETAILING MY CONCERNS AND I HAVE NOT RECEIVED ONE RESPONSE! I SENT MY EMAIL TO A SAMANTHA.
