Cingular Makes Me Grumpy

20 minutes on the phone. What do I have to show for it? Someone has to call me back. My problems thus far:

• phone did not activate properly;
• voicemail did not activate properly;
• phone gives me an echo of my voice sometimes instead of answering calls; and
• I never received a welcome kit with my rebate information.
  

Solutions thus far:

• one phone call last Wednesday morning activated my phone;
• one phone call last Wednesday afternoon activated my voicemail; and
  
• one phone call today, transferred to three different people, means a second welcome kit will arrive in 3-5 business days. Phone still echos.
