Poor calls on LTE and 3G networks

<p>Whenever I am on LTE or 3G networks on my phone and make calls the calls stutter and cutout as if poor signal even if the signal is full. I have called in and they disabled my WIFI calling but the problem still persists. I was making banking calls today and all my minutes and airtime is depleted as a result of this connection issue where I had to repeat myself over and over again to get the information across aswell as request the person I was talking to to repeat themselves. A call that would have taken less than 5 min to complete took a whole half hour due to these issues. I am truely dissatisfied </p>
