Customer Service Complaint

Jeez.. where to start:

Had two accounts merged into one, with telephone numbers forwarded.. Those forwarded numbers stopped working - found out about it from a client!
1. Still waiting to find out:
2. 1. Why they stopped working
  2. When they stopped working - has cost our business thousands of dollars and potential new clients.
Customer Service
1. Live Chat Agent Rowell B ended the conversation before finished with concerns.
2. Live Chat .. received a preliminary message from Rohit, but the conversation ended before I could reply
3. Called account manager, Ma. Rhona Magallanes, and was hung up on. When I called back, I received a message that she was not available. (FYI live chat agent, Maribel, said that the account manager was available 0600 - 1800 PST, and I called within that timeframe)
4. Live Chat conversations were ended prior to being able to interact with an agent twice
5. Created a support case. I received an email from Kim Santos (Global Customer Care) asking for a phone number & a better time to call. When I responded back the next day, received an auto-reply that the case had been canceled.
6. 1. In finally getting access to Adriane via live chat, they said that the support case was canceled 4 MINUTES after it was created. The reason was a duplicate support case, but I was NEVER INFORMED of the other case number by Kim Santos - nor was information offered about that case number by Adriane.
