Terrible signal and no call backs despite request

<p>Good day</p> <p> </p> <p>I am trying to get assistance from channel islands. I phoned through the app (I am assuming you are using data instead of voice to contact the call centres) and the signal is ALWAYS terrible. I have to keep repeating myself and eventually get the information I need.</p> <p> </p> <p>When I called channel islands, I had to speak to TWO different people and both times I asked the person to call me back because they could not hear me. I have not heard back from either of them</p> <p> </p> <p>I am beginning to wonder whether the channel islands registration was a good idea.</p> <p> </p> <p> </p>
