Query: Too complicated, poor quality

I got this so that I could use a headset. When I use the headset, people can't hear me. Now the digital display has gotten garbled. As a result, I can't tell if phone is muted or not, so I need to purchase a new phone. It's not easy to find phone numbers one adds to quickly dial (except for 3). Don't get this phone!
